Cycling Base Layers

Pulling on an extra layer when the thermometer's rising might seem counterintuitive, but a proper base layer, like the Men's SL Short Sleeve Base Layer, can make all the difference. Wearing a lightweight base layer helps wick sweat away from the body, generating an even greater cooling effect. This is all due to the wicking properties of our VaporRize mesh fabric. To top it off, features like soft-puff stitching eliminate abrasion-inducing seams, while our Slim Fit conforms to your body. - VaporRize mesh fabrics are engineered to rapidly wick moisture away from the skin, keeping you cool, dry, and comfortable in any condition. - Cycling-specific fit and construction complement your movements in the saddle, while also allowing ample room for layering, eliminating bulk. - Soft puff stitching gets rid of chafing by greatly reducing the number of seams. - Form Fit closely and precisely conforms to the curves of the body, ensuring an unrivaled level of fit.

When you go by bike, some rides call for just a bit of cushion without the bulk of a standard cycling short. That' where the Minimal Liner Short comes in. Think of it as an upgraded pair of boxer briefs with our slim and breathable Versa chamois. This is your go-to liner for hot laps on your favorite trail, a day of lift access shredding, or your daily commute.

The first goal of this base layer is to move moisture away from your skin while adding minimal insulation for those cool days when your riding intensity is high enough and your outer layers are warm enough. The areas covered by the bibtight around the waist and up the back can get hot, so we used a lightweight PrimaLoft fabric to help even out the temperature. This baselayer works best when in contact with the skin, so both fabrics are very stretchy and the cut is slim. On extremely cold days we'll use this as a first layer under a Flanders Warm second base layer, or under a thermal jersey. It's very effective at moving sweat away from the body. - Proprietary stretch rib knit 100% polyester main body fabric with Prosecco hydrophilic treatment for maximum wicking - PrimaLoft panels at waist and back where bibtight covers the upper body, to reduce uneven insulation - Crew neck closure to fit under short-collared jerseys
