Assos GTO Winter Dermasensor Long Sleeve Base Layer
A truly exceptional choice for battling winter conditions, Assos' GTO Dermasensor Long Sleeve Base Layer keeps you warm and comfortable thanks to advanced material and construction.

The material is odour resistant, super soft, breathable, stretchy and highly durable and offers a second-skin fit that hugs the body without feeling restrictive.

About Assos
Swiss precision. Half a century of obsession.
Assos of Switzerland was founded in 1976 by Toni Maier-Moussa with a single ambition: reinvent cycling apparel from the inside out. The Lycra cycling short, modern bibs, the chamois as we know it — all began here. Half a century later, the obsession with precision and ride feel hasn't moved an inch.
Assos still designs and engineers every piece in Switzerland. The brand operates its own laboratory, its own development pool of test riders, and its own assembly line for the most demanding garments in the range.
