S3® Technology

Silver ions bind to and penetrate the surface of odor-causing bacteria on contact. Silver ions disrupt the microbe's DNA, preventing the formation of odor and keeping your garments fresher, longer.

4-Direction Stretch

Superior comfort, fit and freedom of movement. The inherent multi-directional stretch of the fabric allows you to perform the movements needed to hunt without worrying about your gear binding up.
