Water vapor permeability testing

What keeps you dry & cool during a heavy workout? You'll want the fabrics you're wearing to have good water vapor permeability. That means body moisture can get out with ease. Dry and comfortable body, lower body temperature.

 

All Xpore nanoporous membranes are tested according to the JIS L1099 A1 standard to ensure a high degree of water vapor permeability.
