The extremely lightweight and superbreathable Tshirt wicks moisture away from the body very quickly and absorbs almost no moisture. The Tshirt basically dries on the move, right on the body. The basic material of the Tshirt is 100% polyester with Polygiene antibacterial treatment, which significantly eliminates the smell of sweat. The double, shaped collar protects the neck from diaper rash from the straps of the backpack/vest, and of course there are reflective accessories around the entire circumference of the Tshirt. Shortsleeved, longsleeved and tank top designs are available.
