Clean cut and comfortable, this short sleeved ‘Supersonic’ tee from Descente ALLTERRAIN is cut from SHADAN® Premier Guard fabric that not only has a UPF (Ultra Violet Protection index) of 50+, but also acts as a thermal barrier that reflects infrared light, which produces a cooling effect. Highly absorbent and quick drying, this technical style is constructed with ultrasonic welding that allows the fabric to retain all of its original elasticity – the absence of all stitching makes this piece smooth and ergonomic with every wear.
