Clothing Baselayers - Mens

Specialized SL Sleeveless Base Layer

The sleeveless summer weight base layer is the most popular option. Dressing in layers is not just for cool or cold weather, and more and more cyclists are adapting to the concept embraced by pro's for years. Pulling on an extra layer when the thermometer's rising might seem counterintuitive, but a proper design, like the Specialized Men's SL Sleeveless Base Layer, can make all the difference in keeping you cool and dry.

Wearing a lightweight base layer helps wick sweat away from the body, generating an even greater cooling effect than wicking jersey alone. This is all due to the wicking properties of Specialized's VaporRize™ mesh fabric. This version is engineered to rapidly wick moisture away from the skin, keeping you cool, dry, and comfortable in any temperature. Construction-wise, the minimal bulk SL Sleeveless features soft-puff stitching that eliminate abrasion-inducing seams, while the true Slim Fit cycling cut stays where you want it as you go through the various physical movements of riding, in and out of the saddle.
