Assos GTO Spring/Fall LS Dermasensor

The Assos GTO Spring/Fall LS Dermasensor is a long-sleeve baselayer built for riding through the cooler shoulder seasons — that awkward stretch where temperatures shift mid-ride and standard base layers leave you either clammy or cold. Constructed using a 3D jacquard warp-knit fabric, the Dermasensor works as a single seamless piece rather than stitched panels, which means nothing rubs, nothing bunches, and it sits against your skin like a second layer of it.

Assos cut this baselayer in their regularFit, which keeps things comfortable during longer efforts without feeling restrictive under a jersey or jacket. Raw cut edges at the sleeves and waist remove the need for hems entirely, so there's no bulk when layering — it disappears under your kit the way a good baselayer should. The fabric is designed to regulate moisture and manage odor while maintaining warmth in cool conditions, making it a reliable choice for spring and autumn riding when the weather rarely cooperates.
