Does 37.5 Technology wash out?

No. 37.5 active particles are permanently embedded at the fiber level, work for the life of the product, and will not wash out during laundering.

Will I feel the difference?

In independent consumer testing, users consistently prefer products with 37.5 Technology. For example, in one consumer test of insoles made with and without 37.5 Technology, 95% of users preferred the insole with 37.5 Technology for thermal management and 89% preferred the insole with 37.5 Technology for moisture management.

What happens if my 37.5 product eventually ends up in a landfill?

There are very few end-of-life recycling options for textile products, and it takes many centuries for synthetic textiles to biodegrade in a landfill. All 37.5 materials now include an enhanced biodegradation additive to accelerate the natural breakdown of yarns and fibers in a landfill environment and reduce the burden of plastic pollution. 

What does “sustainable thermoregulation” mean?

37.5 Technology is the only thermoregulating technology to combine natural active particles plus enhanced biodegradation and recycled yarn options. So, you do not need to choose between sustainability and performance.  

How has 37.5 Technology been proven to increase performance?

In a study done by scientists at the University of Colorado Boulder, thermoregulation clothing with 37.5 Technology was scientifically proven to increase athletic performance by up to 26% by reducing the increase of core temperature during activity. Proven to decrease the rate of core temperature buildup and keep you cool more effectively than wicking. Scientifically …

How can a fabric both cool you when you’re hot and keep you warm when you’re cold?

Trapped moisture in your clothing, footwear or bedding is an amplifier, making hot feel hotter and cold feel colder. 37.5 Technology works with your body to adapt to its needs, keeping you in your ideal comfort zone longer. 37.5 particles absorb the infrared energy that your body naturally emits, powering the particles to either speed …
