The Magic of AdapTex™
POWERED BY 37.5® TECHNOLOGY
F.A.Q.
Frequently Asked Questions
What is temperature regulating fabric?
The human body constantly produces heat, regulated by releasing moisture vapor from the skin as sweat. AdapTex™ powered by 37.5 Technology fabrics use ultra-porous minerals to increase surface area, attracting and removing heat and moisture before sweat forms. This helps keep you cooler when hot and warmer when cold.
What is the main benefit of AdapTex™ 37.5 Technology in apparel products?
AdapTex™ powered by 37.5 technology speeds evaporation and removes humidity, balancing temperature, controlling moisture, and keeping you in your comfort zone longer.
How can AdapTex both cool you when hot and warm you when cold?
Trapped moisture makes hot feel hotter and cold feel colder. AdapTex™ powered by 37.5 Technology particles absorb your body's infrared energy to speed evaporation when you're hot and retain warmth when you're cold. This technology adapts to individual needs, keeping both cold and hot sleepers comfortable.
Will I feel the difference?
Yes, consumer tests show that 95% of users prefer apparel powered by 37.5 Technology for thermal management, and 89% for moisture management.
