Some people want to get the most out of everything they do.

Sleep harder when sleeping. Relax harder when relaxing. Work harder when working. Train harder when training. Run harder when running. Cycle harder when cycling. Climb harder when climbing.

They treat every part of life like its own extreme sport. Those are our kind of people.
That’s why everything we make maximizes people’s performance and comfort when tackling life’s activities. All of them.

How It Started

37.5 Technology was created by Dr. Gregory Haggquist, a Ph.D. photo-physical chemist and inventor. In 1992, while Dr. Haggquist was in Japan on a JSPS post-doctorate 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, when Dr. Haggquist 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—Haggquist focused on reducing humidity next to skin to maximize evaporate cooling. And it turned out by enhancing comfort human performance was increased by reducing core temperature buildup. Now you too can experience the same phenomena volcanic sand bath experience when wearing apparel and footwear made with 37.5 technology.
