Fabrics with 37.5TM Technology
In fabrics with 37.5 technology, patented active particles permanently embedded at the fiber level capture and release moisture vapor. 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 garment remains.
Cocona fabrics work brilliantly alone, but the performance gets even better when layered—the whole is truly greater than the sum of its parts. When base layer, mid layer, and outer layer are all made with 37.5 technology, each layer actively works together to create accelerated drying of the entire system.
A wide range of fabrics are made with 37.5 technology, and more are being created every season. Our mill partners currently offer fabrics with 37.5 technology in the following constructions:
- Natural fibers such as Merino wool, cotton, Tencel®, etc.
- Synthetic Knit Fabrics
- Fleece and Softshell Fabrics
- Woven Fabrics
- Footwear fabrics
- Glove insert fabrics
