What is VENEX Recovery Wear... Unlike training wear intended to improve performance during exercise, or compression wear aimed to create an environment that is difficult to fatigue, this garment was created to provide a "easy to recover environment" without hindering recovery support. PHT is a special material from VENEX, which is woven with nano-platinum and minerals. This special material is "PHT" that blends nano-platinum and minerals using the latest technology.This PHT gently hugs your body and makes you feel relaxed.Venex is made of each PHT kneading into the fibers so it will stay permanently no matter how many times you wash it. Venex has acquired an EPC patent in 34 countries around the world as a patented technology in December 2011.
