Assos ThermoBooster P1 base layer top long sleeve matte black - XS

The Assos long-sleeve base layer is a versatile, foldable, and ultra-breathable thermal layer for high-intensity cycling, updated with pockets for use as a jersey in cool conditions or as an intermediate layer for additional core protection in the coldest and most demanding conditions. The new thermal fabric is a highly elastic warp-knit that wraps around the body's contours with an aerodynamic silhouette. It is also sufficiently breathable for all-out efforts, and if the temperature or riding intensity becomes too high, the ThermoBooster P1 compresses to the size of a rain jacket for storage in a jersey pocket. Its versatile fabric and second-skin fit adapt to all seasons: wear it over a base layer or a summer-weight jersey in spring and autumn, and place it beneath storm-proof protection for enhanced thermal regulation in mid-winter.
