Engineered for speed, the Castelli PR 2 Speed Suit features optimal aerodynamics and superior all-day comfort for half and long-distance triathlons. The upper body features a smooth, lightweight 50d fabric, with the bottom half using a Premio-based fabric to improve aerodynamics in any condition. Included in the shorts is the KISS Tri pad to keep us comfortable on the bike and moving freely on the run, while two rear pockets provide plenty of room for snaks.
