Body Paint San Remo Tri Suit SS

Based on its one-piece aerodynamic cycling kit by the same name, the San Remo short sleeve tri suit is designed for speed on the bike. Castelli has found that exposed shoulders create measurably more drag than shoulders covered with certain fabrics, and this suit has covers the shoulders and upper arms. According to Castelli’s testing, it is 2/3rds as effective as the T1 Stealth Top at reducing aero drag while cycling, yet doesn’t have to be put on or taken off during the race. One drawback to the always-on speed suit is temperature regulation. Covering more of the upper body during the run could reduce heat dissipation, so the San Remo tri suit is best used in cooler races.
