Our Short Sleeve Base Layer is designed to keep your body dry during mild & warm conditions. It is made out of antibacterial DRYARN® fabric. The fabric doesn’t absorb moisture, but transports it away from your body, helping to maintain a constant and optimal body temperature. The touch and feel of this base layer is stretchy and comfortable thanks to the non-irritating flat stitch seams. You won't even notice you are wearing a base layer. It is made out of a super thin, thermo-regulating material that is fast drying as well.
