Footwear & Accessories
Best Foot Forward
When moisture gets trapped in footwear and accessories, it makes hot feel hotter and cold feel colder. 37.5 Technology works to actively remove heat and humidity, so you stay dry and comfy while on the move. Patented 37.5® Technology uses natural minerals to speed evaporation, redirect heat energy, and boost performance.
Sustainable to the Core
You no longer have to choose between sustainability and performance. 37.5 Technology harnesses the power of natural minerals to create sustainable temperature regulating fabrics, insulations, foams, and laminates. Get moving with our chemical-free performance technology.
Study participants preferred cooling insoles with 37.5 Technology by an overwhelming majority.
37.5 Technology traps odors and releases them when laundered or cleaned. Users have found fabrics made with 37.5 Technology stay fresher, longer.
Yes, wear testing has confirmed users prefer wearing the temperature regulating clothing made with 37.5 Technology.
No. 37.5 active particles are permanently embedded at the fiber level, work for the life of the product, and will not wash out during laundering.
In a study done by scientists at the University of Colorado Boulder, thermoregulation clothing with 37.5 Technology was scientifically proven to increase athletic performance by up to 26% by reducing the increase of core temperature during activity. Proven to decrease the rate of core temperature buildup and keep you cool more effectively than wicking. Scientifically proven to increase stamina by reducing the amount of energy used to manage core temperature. Proven to increase efficiency so you use less energy to do the same amount of work.

No. 37.5 Technology is made from naturally occurring volcanic minerals. It is not a chemical finish and does not contain harmful chemicals.
37.5 Technology speeds evaporation and removes humidity next to your skin, helping to balance your temperature, control moisture and keep you in your ideal comfort zone longer.
