Oakley Endurance Base Layer Sleveless

"High performance starts here. The men's Endurance Sleeveless Base Layer is the first step to lasting comfort and performance without breaking a sweat. This sleeveless model is the answer to Oakley's short-sleeved base layers, which take cooling to the next level thanks to the underarm opening for additional freedom of movement and air circulation. The breathable mesh material is form-fitting, stretches in four directions and wicks moisture away immediately thanks to Hydrolix technology. Wear it under an Oakley jersey and you have the ultimate training partner that keeps you dry and fresh and allows you to perform mile after mile."
