how it works while you work

XOSKIN™'s RAPIDriCOPPER™ technology reduces body heat by decreasing the skin to fabric friction while at the same time moving moisture faster over the PTFE fiber matrix causing the fabric and skin to stay dryer and cooler. The ionic copper fiber matrix reduces odor causing bacteria while helping to promote skin wellness and a healthier environment for the skin.

  • 3.3D XO-AirFlowSPHERES
  • 4.3D XO-AirChannelDUCT

The complex system of engineered knitted zones operates in cold or warm weather by developing an interior dynamic that effectively reduces kinetic friction and increases moisture movement and dry times by thermal dynamics because of the uniquely designed 3D sweat traps and air channels knitted into the construction.
