Practical for challenging training in the mountains: The Sertig Headband keeps your hair in place and absorbs sweat. The headband features an impressively lightweight, pleasant, stretchable material that feels good against the skin. Active moisture-wicking prevents rapid overcooling by transporting sweat away from the body. The antimicrobial FreshGuard® treatment prevents unpleasant odors. If you don't want to wear your headband during your training session, its small packing volume means that you can stow it in your backpack.
