The fit is excellent but loose enough to wear a base layer underneath. My child's measurement comes at upper range of 2T so we got 3T. The fit was still very good with plenty of room to grow into.
Bought for our 27 mo. Granddaughter. Great fit. Used almost daily for swinging, slides and playing in the dirt. Perfect for protecting those young knees. Will buy again.
Bought both 3T & 4T in bright coral. These pants fit perfectly on my 3 yr old son. 38.5 tall, about 32 lbs. ( maybe slightly short for very tall for age child ) so I ordered for next year as well.

The material seems light yet substantial. I am hoping the knees last. The bright color is great for quickly picking out your child in a group. I will try to update how well they hold up. I know this is a lengthy review but we tried many pants ( we like to be fully covered) and these are far superior so we hope Patagonia keeps making them! If Patagonia reads this please consider putting the elastic on the ankles as well. This would be good for bike riding and to cover with socks for tick prevention.
Our boy wears these all the time. Theyre a little short when hes riding but otherwise fit great. Hope Patagonia continues to make them and offers more colors. I would totally wear a pair myself!
