About Us


We are the global leader in sustainable thermoregulation material science.

Created by Cocona Labs, 37.5® Technology utilizes natural volcanic minerals that are permanently incorporated into fabrics, insulations, foams, and laminate materials. This patented technology is proven to help you stay comfortable and perform at your best by helping the body maintain an optimal temperature and relative humidity next to the skin, regardless of the activity. Materials made with 37.5 Technology offer sustainability benefits throughout the product lifecycle and are used across a wide array of industries, including apparel, footwear, bedding and home goods. Cocona Labs is headquartered in Boulder, Colorado.

From performance base layers to breathable office wear, suits to ski gloves,  37.5 Technology improves the comfort and performance of clothing from head to toe.

37.5 Technology dramatically increases the comfort and climate control of housewares, including bedding, mattresses, and furnishings.

37.5 Technology removes moistures and improves thermoregulation so that shoes, socks, and accessories feel and perform better.

Made From Nature

37.5 Technology uses natural volcanic minerals and activated carbon from coconut.

Better Performance

Scientifically proven to increase stamina by reducing the amount of energy used to manage core temperature, 37.5 Technology extends an athlete’s peak performance by 10 minutes—or 26%. This increases efficiency so you use less energy to do the same amount of work.

Better Sleep

Proven to reduce the effect of temperature-induced sleep disruptions, 37.5 Technology leads to longer, more restful sleep cycles, so you stay in your comfort zone more often and longer: 89% of the time vs only 38% with traditional materials.

Less Moisture

Our technology removes moisture in the sweat vapor stage, before liquid sweat forms. Wicking only distributes moisture, which is why 37.5 is proven to keep you drier and more comfortable than wicking.

Balanced Temperature

Using your body’s own energy to speed evaporation and remove humidity next to your skin, 37.5 Technology adapts to help cool you when you’re hot or keep you warm when you’re cold.  

Our Story

How It Started

37.5 Technology was created by a Ph.D. photo-physical chemist and inventor. In 1992, while in Japan on a JSPS postdoctoral fellowship, he was taken to the volcanic sand baths on Mt. Aso. At first, he thought he would only be able to stand the heat for a few minutes, but once buried in the sand he found it not to be hot but comfortable. So comfortable he stayed in the sand for an hour.

What he realized is comfort comes from balance, a balance between heat gain and heat loss. The volcanic sand was removing the sweat vapor from his skin so fast that he was continually cooled by sweat evaporation.

This was the moment of clarity, he understood that removing the sweat vapor before it turns to liquid sweat was key to comfort. While others were focused on wicking—spreading liquid sweat on fabric—he focused on reducing humidity next to skin to maximize evaporative cooling. And it turned out by enhancing comfort human performance was increased by reducing core temperature buildup. Now you can experience the same phenomena volcanic sand bath experience when wearing apparel and footwear made with 37.5 technology.
