Baselayers & Undergarments

An ultralight summer base layer featuring a seamless design and carbon yarns to keep your core cool, dry, and comfortable in balmy conditions. We're constantly refining the first-layer platform in the name of greater moisture management and overall comfort. Such is the case with the new Skin Layer family, taking the baton from our Skinfoils with much lighter designs, refined constructions, and better-performing fiber blends. We've lowered the SS Skin Layer's weight by roughly 25% compared to its Skinfoil predecessor and used a tubular knit technology that's free of irritating side seams. A new blend of carbon and polypropylene yarns have been strategically arranged to manage moisture much better than previous iterations, resulting in a breathable, antibacterial short-sleeved first layer that keeps you cool and dry from the base up. The Circular Seamless construction introduces a tubular knit that's free of side seams, creating an ultrasoft, comfortable feel against the body. The sleeves are sewn directly into the armhole to promote a full range of motion beneath additional layers.

A medium-weight, short-sleeve base layer tuned to keep your core lightly insulated and dry in cool conditions. This protective layer sets the foundation of our ASSOS Layering System, doing the job of keeping your upper half lightly insulated and dry in the cool, challenging conditions of spring and fall. Having been tested over and over again by our product team until we were finally satisfied, the Spring/Fall SS Skin Layer represents a total first-layer reset. A cool-weather-tuned blend of carbon and polypropylene yarns are employed to pull moisture away from your skin and insulate your core, keeping you dry, insulated, and comfortable from the outset. The thicker Circular Seamless construction introduces a tubular knit that's free of side seams, creating an ultrasoft, comfortable feel against the body. The sleeves are sewn directly into the armhole to promote a full range of motion beneath additional layers.

Light insulation, seamless comfort, and full-arm coverage in a long-sleeve base layer for colder conditions encountered in late fall and early spring. It's crucial that our upper body gets an added boost against the elements during those cold fall and early spring conditions. As a solution, we developed the Spring/Fall LS Skin Layer, which has taken the torch from our iconic Skinfoil base layers with a completely revamped design and all-new blend of fibers. To start, we've lowered the weight by about 8% and used a tubular knit technology that's free of irritating side seams. A cool-weather-tuned blend of carbon and polypropylene yarns are employed to pull moisture away from your skin and insulate your core, keeping you dry, insulated, and comfortable from the outset. The thicker Circular Seamless construction introduces a tubular knit that's free of side seams, creating an ultrasoft, comfortable feel against the body. The sleeves are sewn directly into the armhole to promote a full range of motion beneath additional layers.
$120.00
A long-sleeved base layer tuned for the cold, demanding conditions of winter riding, featuring an insulating knit structure and seamless construction to keep you dry and insulated from the base up. Temperature regulation is the key performance indicator of any base layer, and this is especially true for a winter version. But winter poses a specific host of challenges not found in other climaCodes, namely in the form of added cold air and your additional layers. This is where our new Winter LS Skin Layer fills the gap, tuned with a thicker knit "weight," taller collar, and more stretch than our Spring/Fall version for boosted insulation and flexibility under your outer apparel. A winter-tuned blend of carbon and polypropylene yarns—plus elastane— are employed, which draws moisture away from your skin and insulates your core, keeping you dry, insulated, and comfortable from the outset. The Winter Skin Layer relies on a Circular Seamless construction that's free of irritating side seams. The sleeves are sewn directly into the armhole to promote a full range of motion beneath additional layers.
$135.00
Maximum thermal protection and body-mapped comfort in a long-sleeved base layer, tuned for the coldest, most demanding winter riding conditions. Building on our protective Winter LS Skin Layer, the Ultraz edition turns up the warmth and windblocking capabilities even further with its wool-blended knit. We see this as the ultimate defensive first layer in the most challenging winter conditions, as it goes into overdrive at the core level to keep you dry and your temperature stable. A robust arctic-tuned blend of polypropylene and wool are employed, serving as the ultimate next-to-skin foundation when maximum thermal- and windblocking-protection are most critical. The Ultraz relies on a Circular Seamless construction that's both ultrasoft and free of irritating side seams. The sleeves are sewn directly into the armholes to promote a full range of motion beneath additional layers.

PROSECCO TECH SHORT SLEEVE 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 base layer 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. WHAT IT IS Made to keep you dry in cool conditions, this base layer features body mapping construction with Prosecco hydrophilic treatment on the main body fabric and lighter-weight PrimaLoft fabric aligned to the parts of the body covered by the bibtight straps.
