The extremely lightweight and super-breathable T-shirt wicks moisture away from the body very quickly and absorbs almost no moisture. The T-shirt basically dries on the move, right on the body. The basic material of the T-shirt 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 T-shirt. Short-sleeved, long-sleeved and tank top designs are available.
