The Assos Spring Fall LS Skin Layer P1 is the essential base layer for cool-weather rides, featuring long sleeves for full-arm thermoregulation and moisture management. This latest version is 15% lighter, offering improved insulation in key areas while enhancing breathability for optimal comfort.

Despite its reduced weight, this skin layer provides greater versatility, with increased collar coverage, improved odor control, and a more streamlined, body-mapped fit. The fabric is tightly woven on the front panel for added warmth where it's needed most, while the back and underarm areas feature a more open weave to boost breathability. This design helps regulate your body temperature, expelling excess heat during intense efforts to prevent overheating.
