Less Odor

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.

Longer Lasting

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.

No Waste

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.*


Made from Nature
