GTO Winter Long Sleeve Dermasensor Base Layer - Black Series

The pinnacle of base layer technology, with added insulation for winter cycling. Seamless, breathable, stretchable, durable, and odor-resistant—a high-performance second skin.

Everything a standard base layer does, the DermaSensor does better. Breathability, extreme stretch, compression—no other material transforms the rider like this. Its true seamless construction means that it also layers better than any other base layer, disappearing between skin and thermal layers or winter jackets as a frictionless second skin to maintain a dry, warm microclimate in frigid conditions.
