Odor-Control Additives

Odor-control additives block or prevent the growth of odor-causing microbes.

Why

When we sweat, body oils and dirt create an ideal growth environment for odor-causing bacteria to thrive. Although sweat is odorless, these microbes can convert it into something quite smelly. Textiles with odor-control additives inhibit the growth of the odor-causing microbes.

Odor-control additives aren’t only about smelling sweet. Although the most energy-intensive part of a garment’s life cycle is production, laundering is the second most impactful, so reducing the number of washes saves water and energy. Anti-odor treatment keeps your garment smelling fresh and prevents the buildup of persistent odor over time, which allows you to increase the number of wears between washes and to extend the overall lifetime of the garment.

Where We Are

Patagonia currently uses HeiQ® Fresh durable odor control additive on select styles (e.g., baselayers and other next-to-skin applications). HeiQ® Fresh is a silver-ion-based odor-control additive. While some silver-containing technologies can have adverse environmental impacts, we have carefully chosen this technology because it is able to provide good performance with minimal environmental impact.

What’s Next

We are always evaluating and field testing new anti-odor technologies to find the best performing treatment with the lowest environmental impact that can still keep your shirt smelling fresher for longer.
