Louis Garneau 2017 Men's Tri Course M-2 Triathlon Short Sleeve Jersey - 1020903 (Black/Bright Yellow - S)

The Tri Course M-2 is a jersey that's tuned to the needs of the triathlete. The ergonomic fit is designed to follow the contour of your body, with minimal excess fabric to create drag for a winning combination of comfort and performance whether you're wearing it beneath your wetsuit or on the finishing stretch of the run.

While the wind tunnel testing for maximum aerodynamics has pushed athletes toward racing in a short sleeve tri-top, many triathletes still prefer the coolness and comfort that comes when racing in a sleeveless tri-top. While the Castelli Free Tri 2 Sleeveless Top may lose a few seconds, it is still fast but much more comfortable on the run and cooler in hot weather. The comfort and cooling features may conversely help a triathlete in his performance.
