What is our new 37.5 material?
37.5 Technology is a dynamic thermoregulation technology that triggers off of humidity.
It helps keep your body at the ideal core temperature of 37.5° Celsius and helps keep the microclimate next to your skin at the ideal relative humidity of 37.5%.
It’s also been proven to increase comfort by removing moisture in the vapor stage, before liquid sweat forms, to delay the onset of sweat.
How does 37.5 material work?
37.5 Technology triggers off of humidity. Humidity is the gauge for whether you are hot or cold. When you’re hot, active particles embedded into the material use your body’s energy to remove moisture and cool you down. When you’re cold, the active particles retain the body’s energy to warm you up.
Patented 37.5 technology uses active particles made from volcanic sand that have billions of micropores, massively increasing the surface area of the material. These particles also absorb infrared (IR) light in the spectrum that the human body emits it, and this light becomes the energy that powers the particle. If no moisture (sweat vapor) is present, meaning you are cool, the particles retain this energy to warm you. If moisture (sweat vapor) is present, meaning you are hot, the particles use this energy to move moisture out of the clothing system. Without these active particles, water has no reason to leave the microclimate until relative humidity is much higher than is comfortable. 37.5 active particles also trap odor molecules and then release them when they’re washed and dried.
Will the technology in 37.5 material ever fade?
The active particles are permanently embedded in the fiber they will last the lifetime of the garment.
