Scientifically proven to increase stamina by reducing the amount of energy used to manage core temperature. Extend the wearer/ athlete's peak performance by 26% or 10 minutes. Increase efficiency so you use less energy to do the same amount of work.
Remove moisture in the sweat vapor stage, before liquid sweat forms. Delay the onset of sweat.
Wicking only moves moisture, 37.5 removes moisture. Proven to keep you dry more effectively than wicking; thus increasing your comfort.
When you are hot, 37.5 speeds evaporation and cooling; when you are cold, 37.5 returns the energy to warm the body. A shirt with 37.5 technology has the same effect as an ice vest on cooling the core.
Decrease the rate of core temperature buildup.
The 37.5® particles are obtained in a natural fashion, are mild on the skin and are hypoallergenic. The Kuul Thread shirt consists of a pure cotton blend and high tech fiber with volcanic sand.
37.5® will help cool you down when you’re hot so you can tackle a long shift, tense meeting, twenty block walk, summer wedding, and run through the airport all without breaking a sweat.
The active 37.5® particles are integrated in the yarn with permanent effect so it will last for the lifetime of the garment, including the odor control.
Enhanced performance thanks to optimum core temperature and humidity. 37.5® helps you maintain a comfortable personal microclimate relative humidity of 37.5%.
Patented 37.5 Technology uses active particles made from volcanic sand that have billions of micropores, massively increasing the surface area of the material. If moisture (sweat) is present, meaning you are hot, the particles use this energy to move moisture out of the clothing system. Active particles also trap odor molecules and then release them when they're washed and dry. And speaking of washing, because the active particles are permanently embedded in the fiber, they will last the lifetime of the garment.
