The Raide RaceTech Shirt is built from a micro dot air fabric engineered to move air and disappear on the hottest runs. Pit vents add extra airflow right where heat builds fastest, while merrow stitched seams and a bonded hem keep the low-profile fit clean and chafe-free under a pack or belt. An integrated stow pocket packs the shirt away when the temperature calls for going shirtless, or holds ice at the base of the neck to turn the same pocket into a cooling system, all while UPF 50 fabric covers exposed skin on sun-heavy climbs. What Our Gearhead(R) Experts Are Saying:"I forgot I had it on halfway through a hot tempo run, and the pit vents kept me from ever feeling like I was overheating."
