Goodbye at last, merino Long Johns

These replaced my old Pata merino wool long underwear. I resisted for a long time because of the way some synthetics can feel, but they nailed it with these. Super comfy on the skin. Loose enough that I can climb or ski in them without relying on the fabric stretch entirely, but tight enough that they slip on under outer layers without issue. I als... Read Moreo feel fine wearing them as a warm layer for sleep while camping.

February 13, 2023

So so much more than a base layer!

These are deceptively warm under my lightweight, no-insulation snowboard pants. Coupling these with a lighter ski/riding pant seems to make for a less bulky, better functioning pant on the coldest of Vermont-cold days. This thermal layer is absolutely a much warmer layer than the Capilene mid weight, making it much more than just a base layer. So g... Read Morelad to add these to my quiver!

Great long Johns

Some of the reviews on here report an odd fit, which they definitely have. They are kinda bagging leggings with a secure waistband. I have furry tree trunk legs so that was awesome for me! I wear 35waist and usually need a relaxed/athletic cut pant or a stretch material slim cut - so These fit me perfectly. I could see how if you have little baby c... Read Morehicken legs you would probably want to shop down a size or hit the gym. Yeah idk if people want long Johns to fit like strink wrap tubing around your downstairs mix-up but I hate being suffocated by sweatpants and thermals when skiing or running so these are probably the best baselayer bottoms Ive ever owned bc fit. They seem so thin and light but are stupid warm. For resort skiing in Montana above 10F I would just wear these plus my bibs and I dont notice my legs at all.

Very well made and surprisingly

I like the long Johns

I like the long Johns overall the waist fits me well (I wear a 32). I like the fabric but if Patagonia offered something a little heavier I would buy it. My main feed back is the legs are a little baggy at least in part because the are longer than other l.J.s I own . This is mainly an issue when pairing them with work pants, just too much fabric. ... Read MoreFit especially in pants and bottoms is a possible place for improvement for Patagonia. I have been buying Patagonia products since the early 80s so I am a fan of the products the mission and the service. Thank you for your consideration Kelly Ray Mathews

January 14, 2023

Great material!

Love this material - it is light and breathable but very warm. I have big legs and it is tough to find slimmer garments that fit me decently. The calves are a bit tight and pulling them up above my ski boots is a bit uncomfortable so I would prefer a bit wider fit in the calf area. Very pleased with my purchase!

January 12, 2023

I bought these for additional

I bought these for additional warmth while skiing. Unfortunately, the ankle cuffs are very large, untapered, and without elastic. This would require folding the excess material around the lower leg which is intolerable in well fitting ski boots. They would likely work well for all other applications and seemed well made otherwise.

Go-to thermals

I have three pair of these. They're basic thermals that I layer if I need more warmth that one pair provides. I'm 6'1, slim, and long-limbed, and these fit me well for length and waist. My only negative observation would be that on two of the three pairs, the elastic at the ankle is looser than I would prefer, but for me it's us...

December 29, 2022

High quality

Like everything Patagonia makes, these are high-quality thermal bottoms. Comfortable and warm. My only criticism is that the inner fly piece is too small, fly opens too easily, still very functional though

December 28, 2022

Warm as ever when skiing.

These base layer are fantastic. They have what I would call a waffle weave which makes them super comfortable. They are thinner than expected but super warm.

December 26, 2022

Super light and not restrictive

Super light and not restrictive of movement, but surprisingly warm in spite of being essentially weightless.

December 25, 2022

Great product

Wear for work

December 23, 2022

Super Comfortable

Little baggy in the fit, which is nice for ski touring. Makes an awesome below the bibs layer for 20-35f temperatures. Breathes well, fairly warm. I catch myself not thinking about them all day, which is usually a sign of great gear to me!

Say Goodbye to Cold Legs

I bought this specifically for the cold, wet and windy Cape Town winters when you gotta be outside but don't want your legs to freeze. I'd wear this under a pair of jeans and they were brilliant. I've attended many outdoor events with them as a baselayer and they are phenomenal at retaining warmth. Indoors, they can act as comfy swe... Read Moreatpants that are stretchy, very light and incredibly warm. They are a tiny bit see-through. As with most of the capilene air line of clothing, the wool can be a bit itchy the first time you wear the clothing, but you get used to it and the abrasion subsides quickly, nothing to really worry about.

December 12, 2022

Ive used these for hunting

Ive used these for hunting (sitting) so far and Im stunned at how much heat they can trap for being so light weight. Amazing.

At 79 yrs my activities

At 79 yrs my activities are more sedate now - hiking, fast walking, photo-ing, some biking, etc. These thermal weight capalene base layer pants are warm, comfortable, fexible allowing for much movement - ie pedaling, kneeling, lots of bending etc - some stretching out but still maintain fit and function. Worn under shorts they keep me plenty warm, ... Read Morealthough in rain when wet they lose some warmth. Some snagging but easily repaired. My second pair, highly recommend for somewhat passive activities , ie wallking hiking etc (don't know how they work in more extreme applications)

November 20, 2022

Warm but restrictive

I have other base layers that are much less restrictive. This garment is bulky and the waist band is too thick and tight. To make them work, you must have oversized outer wear for comfort and freedom of movement. Not exactly what I was expecting.

Response from Patagonia
November 29, 2022

Hey Ira, thanks for the review. We're sorry to hear that it didn't work out with these bottoms. Our thermal weight baselayers will be the thickest option available. If you were looking for something more lightweight, but still warm, we recommend checking out the [Men's Capilene Air Bottoms](https://www.patagonia.com/product/mens-capilene-air-baselayer-bottoms/36556.html?dwvar_36556_color=FGX&cgid=root).

Warm, comfy, lacking in durability, big floppy ankles

Was taking a trip to Ecuador to climb some Andean peaks, including Chimborazo, the closest you can get to the sun on Earth. I tried half a dozen different baselayer before settling on these. These were the warmest of all the baselayers I had tried. But were really lacking in durability. Pros: Warm Comfortable Non-black color is cool Cons: -Durabi... Read Morelity. I have only worn them once, for about ten hours, and they are already showing more wear and tear than other baselayers I have had for a decade or more. No other baselayer has shown this much wear and tear, even when worn with the same shells. Doesn't bode well for long term lifespan. -Loose ankles**. This is totally a preference thing. There are two groups or opinions here. One group of people like loose ankles, and they pull the ankles up to their calves to keep them out of their ski boots or mountaineering boots, which causes bunching of fabric up around the calf. The other group of people likes snug tight fitting ankles that go inside the boot(s). Being snug prevents folds, wrinkles, and pressure points. I am in the latter group. So while SOME people may appreciate the loose floppy ankles with tons of extra fabric, I don't. I'd definitely want them more snug. Think about which group you belong to. All things considered, would not buy again, not even at half price. Maybe if I could get them at 70% off or more, but even at 50% off, they're not worth it. I have a 31" waist and inseam, and the small fit well (except the big baggy ankles...)

Odd fit

As others have noted, the fit is odd, with a tight waist but somewhat baggy legs. I bought one size smaller than my usual, and it mostly worked OK. The material is lighter and thinner than I expected, but it performed well on a rafting trip where I wore it nonstop. All in all, a good product.

October 15, 2022

Great base layer

I use these for skiing under my shell pants and they work fantastic, great warmth for colder days without being bulky or restrictive. The fit is on point and they feel great on skin.

My other bottoms are size medium and the fit is perfect. This one is huge, away to baggy house under my waders.

Returned Them

I was expecting something different than what these were. These long underwear were what I would call light weight. I was looking for something much thicker for extreme weather. You can see right through the material. I returned them.

July 15, 2022

8% spandex! fail

Stop putting spandex in these!! You don't need the stretch, obviously, since the mid-weights are 100% poly. Spandex isn't breathable and has high moisture absorption .... pretty much the worst combo for long underwear. Come on, y'all should know better than this.

April 29, 2022

Time Will Tell

I bought these in XS (my usual size) when my twenty year old red expedition weight couldn't hold up to one more waistband replacement. The waistband on these certainly appears to do better in that department. In fact, that's why I had to exchange them for a small. The body of the leggings was perfect-- the waistband was absurdly painful (... Read MoreI wear size 28). Even the small is tight enough that I have to keep them under the top of the ilium rather than at my waist. It would be too uncomfortable otherwise. I like the light weight of the fabric, but only time (and a full winter or two) will tell if they can compete with my old red expeditions...

April 22, 2022

Nice and warm!

Fits well and keeps me warm!

April 21, 2022

Good Long Johns

I just took these out on a trip to AK and spent about two weeks wearing them. So far the quality seems good and I liked the level of warmth they provided with breathability. Did well on a day where we went from getting super hot in the sun to getting cold and blasted by wind after dark.

Base layers

Lots of river miles walked in these in some of the coldest of temperatures . Would buy again and again thnx for such great products aloha

Toasty base layer!

Great base layer for ski/snow. Wore this under my Snowdrifter bibs in 30 degree weather and was plenty warm. I feel like it runs slightly small-- I am between an L and XL and this item fits me more like a L. Recommend~

Not Quite Right

Bought these for the light weight fabric to help out with my ultralight backpacking kit. Love the fabric weight(5.7oz for the mediums) and comfort but the crotch and ankles are just too loose. When I stretch my knees as in sitting or climbing, the ankles ride up my legs and it takes some time for gravity to let them settle back down to my ankles. T... Read Morehe loose ankles also allow for wind to blow under them. I've got two pairs of poly/spandex tights from another company that hug my legs from top to bottom and don't ride up. Those are 20 years old and still going strong with heavy use...no holes or anything. If these LW Thermals fit like those do, they'd be awesome.

A Joy to Wear

A perfect blend of comfort and function. It drapes around the leg in a relaxed fit that allows for more stretch and mobility, but never feels baggy or bunched regardless of movement. They also regulate temp so well that I can wear these if im heading to work outside in -40 degree windchills, or if im just lounging around the house at 62 degrees....

December 31, 2021

Slightly baggy, very comfortable.

Great base layer, if you're looking for something that isnt loose fitting, I'd pass. I wore this under my blue jeans while walking around bars in the Alps in December at night, and felt comfortable.

December 21, 2021

Gets the job done

Amazing thermals that get the job done. They offer great warm but I do find a wind sneaking in depending on the outer layer from time to time. So about the fit. For a rough estimate Im 62 and 185lb. I had to order a Medium but Im normally in a large for Patagonia bottoms. Maybe they expect them to fit loose, but either way I have always liked therm...

Fall-Winter Must for Cool Conditions

I live in a cold house no matter the time of year - like 64 degrees max. So I wear these under almost anything during cold spells and feel warm and comfortable.

The Best Ive Ever Had!

Great base

Great thermal base. I wear on cold hikes. And also snowboarding.

October 20, 2021

Actually not too baggy

Yeah, they're a bit baggy, but they're not a decision-killer. I bought these primarily to sleep in while cold weather camping, and now I'm wearing them around the house all the time. Maybe my most favorite Patagucci item

May 19, 2021

An essential winter hiking layer, or casual winter layering piece.

I just bought my second pair of these. My first pair is still going strong after 4 years, but I decided to double up after finding a second pair on sale. These are my favorite base layer for winter hiking in the White Mountains. I wear them under a shell layer in temps below 40F. I've used them down to a -30 windchill and, as I layer them, my... Read More legs don't get cold while I'm hiking. Occasionally in tree cover I find myself venting the sides of my shell pants because my legs can get pretty toasty. My legs do tend to run warmer while hiking. These leggings seem to stay pretty breathable and I'd say they dry on the faster side. These also rule as a casual camping layer in shoulder season, or a under layer in the dead of winter for chilly mornings or casual outdoor activities.

April 9, 2021

Very light and cozy

Like TW crew top this bottom is very light and cozy, comfy and soft. I like this very much and have four of them and like very much and would recommend.

From a flyfisherman

The Thermal bottoms are very comfortable on colder fishing days, though very breathable. No more sweating in the waders when walking longer distances. Great fit, very much recommend it.

Great base layer

I've been wearing Patagonia's capilene for over 20 years now. The comfort of the seams, the durability of the product and the warmth..but not too warm has kept me coming back and will for years to come.

January 15, 2021

love the fabric but needs some tweaks to be perfect

I love this fabric. The fit is truly odd though. First of all the length is about 2 inches longer than I expected. For me that is not a big deal, I actually like pulling it down over my feet when im cold-kickin it. The real peculiarities lie in the crotch and waist area. For one the front flap doesn't overlap; there is basically just a hole ... Read Morethere which is annoying. If I dont wear underwear my junk will just find its way out between the flaps. Secondly there is enough space to fit like 4 pairs of buttcheeks in the torso portion. I can pull the waist bad up to my nipples. its just a very weird combination of form fitting and baggy. I use them to wear over smartwool leggings that fit my body effortlessly. otherwise in order for them to fit as a standalone piece I roll the waist down 2 cuffs and the leg openings up one big cuff. Also the tags are so annoying and in order to return/warranty them you are supposed to keep the STY portion which just happens to be at the bottom of a tag that feels like it is long enough to be tucked in your socks. I still love them strangely enough and I wear them every day (seriously) the fabric and lofting is so amazing that I can deal with the absurd fit. PS the tops fit perfect. Dont change those please.

One of my favorite pieces of clothing

These are great, soft and comfortable and warm.

November 25, 2020

Too baggy

I love Capilene-- all my ski base layers are Patagonia. While the waist fit right on the Medium's, everything else was super baggy. Very 90's style. Wish it was more form fitting as a base layer. I ended up returning it.

November 20, 2020

Fits long

At 5'7 & 138lbs and an avid cyclist, these fit well in the seat and thighs, but are ~4" too long and too large a diameter in the lower cafe. They tend to bunch up in the ski boot.

November 19, 2020

Most comfortable fit

My favorite! Keeps me warm and dry while out being active. Comfortable to wear, not constricting like other brands.

My go-to baselayer.

Patagonia's capilene thermal weight layers are so phenomenal. The cut/fit is great, really comfortable, no bulkiness, and the fabric is much warmer than one might think just holding it, but with an outer layer and/or shell it really does provide incredible warmth, but even more importantly to me: incredible breathability. I tend to run hot and... Read More sweat easily during medium-to-high output activities, so I absolutely need breathability in cold weather and the cap thermals breath SO well and I'm able to perfectly manage heat buildup. I use the cap thermal pants for everything. Hiking/trekking, fly fishing, and especially snowboarding - you name it, I've worn them for it. Don't ever discontinue these!

December 12, 2019

More awesome comfy warmth

Great product good fit. Bought 2 pair 1 M's med and later 1 mens large. I'm a 33/34 waist and the Lg are about perfect, the Med are a little tight at the waist for all day use ( for me).

Although the workmanship was good (as usual) this product does not provide the warmth which the "title" represents. They are likely fine for one who on occasion ventures out of the office, I need a non-see through fabric.

Excellent Breathable Base Layer

I've been wearing Capilene thermal weight bottoms for a little over a year now and I continue to be impressed by their performance. The tops and bottoms are extremely lightweight and pack very well.

I have skied 10+ hours with temperatures in the 10-25F range with only a pair of ski pants on over top and never had the slightest bit of a chill.

You can toss Capilene in the wash and it's nearly dry enough to wear after the spin cycle.

Expedition Weight Capilene Seekers

I've seen quite a few reviews on hear discussing the current Thermal Weight Capilene not being as warm as their predecessor the Expedition Weight Capilene. I believe the current iteration is meant to strike the balance between warmth and breath-ability. However, if you find yourself wanting the warmth of the Expedition weight I would suggest t... Read Moreaking a look at the Men's Crosstrek Fleece Bottoms. They are made from the exact same material as the old Expedition Weight (Polartec Power Stretch). They may not be as tight as other baselayers but aren't too much of a compromise. If you are looking for breath-ability and overall versatility these are perfect. Hope this helps!

Super comfortable, very light and packable. Not super warm, but its breatheble. Cons: waistband get twisted after using.

Capilene thermal bottoms-mens

I haven't used them hiking yet but wore them around the house on a cold evening. They feel very comfy and as warm as expected. They fit well; I'm 5'5" and got a small. Unfortunately, the listed weight was way off; very much misadvertising. They are listed at 4.7oz for a medium and i was told 4.3oz for a small. My small weighs 6.... Read More4oz, about 50% more then the listed weight. As someone trying to lighten their pack with an efficient clothing system, this was very disappointing and has me reconsidering patagonia for other lightweight options like rain jacket. Unfortunately i had worn it around for a couple hours and ripped the tags off before weighing it.

Lightweight and packable,not very warm

I purchased these a month ago. They feel nice and are easy to pack. However,they are not warm. They aren't as warm as my older edition Capilene Midweight bottoms. They aren't as warm as some older,cheaper bottoms I have. If you're looking to save ounces,they're great. If you want to stay warm,go with something else.

Great product

Tested in AK in -44 Degrees F and it was perfect as the base layer of multi-layer system. Love this long underwear!

I'm a long-time fan and customer of all things Patagonia. Very good products for the things I like to do. I also like your support on protecting the environment.

Long Johns

I am a Skier and Fly Fisher,needed a medium weight and heavy weight Long Johns. Couldn't be happier with the Patagonia line. Always top quality,love the companies Environmental stand,and the overall comfort is yet to be matched.

Very Warm

I wore these up to Squaw in February and they kept me very warm and dry. A good fit,true to size.

One could argue these pants are in the gradation between the mid-weight bottoms and a pair of fleece pants,but for me this is not entirely the case,read on. These thermals are ribbed with a 1/2 inch wide horizontal band of insulation and then just the thin carcass material for the the next 1/2 inch. Which in a 3 layer set up below a pair of fleece ... Read Morepants,with the wind and water resistant outer layer,would make the over all set up slightly lighter weight/less bulky but equally as warm,compared to a not ribbed full insulation design. I intended to use these in a 2 layer set up below a pair of rain pants that are not air tight at the ankle,this setup allows a little cold wind up the ankle,which would be of no consequence,if your bottom layer had a full insulation design. Zoom in really close on the web pictures,and you can see what I mean.

The fit in the legs is extremely disappointing.

The legs would fit someone weighing 100 pounds more than my 185. The legs are cut so different and huge than the same exact item in MIDWEIGHT. Compare the specs yourself.

A bit disappointed

Bought these thermal weight bottoms believing they would a good replacement for my 10+ year old thermal weight bottom. They are not nearly as warm of comfortable as the original fleece type offering. I am not saying that they are not useful or well made,but they require heavier shell insulation to achieve the same overall warmth and they just don&#...

They are fine if you know what you are getting,but definitely not an equal replacement for the great expedition weight Patagonia classics.

Love these!

These are great and are a perfect weight for wearing under my shell while backcountry skiing. I got them just before Christmas and I just returned from a hut trip to Canada where we had a week of cold temps (high temps of -20 C on several days). These did a good job of both keeping me warm and also breathing enough so I didn't get too sweaty. ...

a layer of comfort

best long underwear ever... low bulk and super warm with a low profile waistband that makes for a comfortable fit under every layer i have. awesome.

Awesome base layer!

Love the new fabric style. Very warm for the weight and moves with my legs better than the older version.

These baselayer bottoms work great in a variety of conditions. I wore them under lightweight hiking pants with temps in the 40s and was not cold while on the trail. They also work well to layer under jeans for walking around town in the winter,and even inside with jeans they don't feel too hot. I love that I can leave them on all day,whether I...

I tried on the merino thermal weight bottoms to compare and these were a looser fit (more comfortable for me),whereas the merino bottoms were more like tights.
