37.5 technology

Comfort in fabric is dictated by temperature and humidity next to the skin, known as your microclimate. With patented 37.5®Technology, active particles permanently embedded at the fibre level capture and release moisture vapor. Not only do these active particles provide 800% more surface area to the fibre, 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. If the user is cold, the active particles retain this energy and give it back to the body.

37.5® active particles also absorb and trap odour molecules, and then release them when they’re washed. Speaking of washing, the active particles will work forever, no matter how many times you wash our products. Or how many times you don’t!
