37.5® Technology Background

In 2016 I wrote about the 37.5 technology when Mission launched their Vaporactive line of performance wear, powered by 37.5.

Dr. Gregory Haggquist, inventor of 37.5 technology, takes a different approach integrating thermal comfort into clothing.

Instead of focusing on wicking (the distribution of sweat on fabric), Haggquist’s technology focuses on the reduction of humidity next to skin. This maximizes the evaporate cooling effect.

His inspiration came in 1992 when he was in Japan and experienced a volcanic sand bath on Mt. Aso.

While buried in the sand, Haggquist realized that he stayed comfortable because the volcanic sand was removing sweat vapor extremely fast.

As a result, he experienced an ongoing cooling effect.
