Assos GTO Spring Fall Dermasensor base layer

The pinnacle of base layer technology, with added insulation for cool-weather cycling. Seamless, breathable, stretchable, durable, and odor-resistant—a high-performance second skin.  Its true seamless construction means that it also layers better than any other base layer, disappearing between skin and thermal layers or light jackets as a frictionless second skin to maintain a dry, warm microclimate in cool weather.

Featured fabrics
DermaSensor textiles are technologically advanced 3D jacquard warp-knit materials produced as single, finished garments rather than as separate panels that are then sewn together. They provide exceptional softness, breathability, stretch, durability, and odor resistance.

Our streamlined regularFit provides total comfort for long training rides and layering under thermal insulation and shells.

Raw cut
DermaSensor construction allows eliminates hems on the sleeve and waist, reducing bulk to facilitate layering. The raw cut sleeves also allow for alterations by simply trimming the sleeves to fit.

Seamless Construction: Eliminates friction between the rider and other equipment layers.
