Wicking fabrics simply spread moisture. Climate control fabrics with 37.5® Technology actually remove moisture vapor before it turns into liquid sweat, so you stay in your comfort zone longer.

Unlike other synthetic materials, our natural minerals trap odors and release them in the wash. Products come out smelling fresh—wash after wash, use after use. You can count on the temperature regulating fabrics and materials powered by 37.5 Technology to smell good no matter how much wear they get.

*Enhanced Biodegradation: 74% biodegradation of 37.5 PET staple fiber in 726 days, reducing to the 37.5 volcanic mineral, titanium dioxide, carbon dioxide, methane, and biomass. The stated rate and extent of degradation does not mean that the material will continue to degrade.

We engineer our high performance yarns and fibers to stand up to a lifetime of wear and tear, but then to break down faster than traditional synthetics in a landfill environment. Unlike other synthetic yarns that sit in landfills for centuries, 37.5 sustainable yarns break down to naturally occurring materials over decades.*

Our minerals are permanently embedded into fibers and yarns so that they never wash out, wear away, or stop performing. The responsive textiles and materials powered by 37.5 Technology perform better than traditional synthetics, even with heavy, daily use.

A study at CU Boulder recorded up to a 26% increase in athletic performance while wearing thermoregulation clothing powered by 37.5® Technology
