Helps Control your core temp

No matter the activity or weather

Comfort in clothing is dictated by your temperature and the humidity next to your skin, known as your microclimate.

How It Works

With patented 37.5® Technology, active particles permanently embedded at the fiber level capture and release moisture vapor.

37.5 Technology Illustration

Not only do these active particles provide 800% more surface area to the fiber, they also provide a unique driving force to remove moisture vapor unlike any other technology.

By actively responding to body heat, the particles use this energy from the body to accelerate the vapor movement and speed up the conversion of liquid to vapor, significantly increasing drying rates. This means the hotter the user gets, the stronger the driving force removing moisture becomes—and the more comfortable the microclimate remains.

About 37.5 Technology

Odor Trapping and Lifetime Lasting

37.5 active particles absorb and trap odor molecules so your clothes don’t smell, and then release them when they’re washed.

Speaking of washing, the active particles will work forever, no matter how many times you wash your clothes. Or how many times you don’t.

Exponentially more cooling power with 37.5® Technology promotes better and longer performance
Fabrics with 37.5® Technology have less odor retention
Fabrics with 37.5® Technology provide UV protection

How It’s Made

37.5® TECHNOLOGY IS MADE FROM NATURE

Our patented active particles are made from volcanic sand and activated carbon from coconut shells.

These microporous particles have the perfect combination of energy absorption and massive surface area to trap moisture and process it out of your microclimate.
