Assos Spring Fall Thermobooster P1

The new thermal textile is a highly elastic warp knit that wraps your body’s contours with an aerodynamic silhouette. It’s also breathable enough for full-gas efforts, and if the temperature or riding intensity get too high, the ThermoBooster P1 compacts to the size of a rain jacket to stow in a jersey pocket. The versatile textile and second-skin fit span seasons – wear it over a skin layer or summer-weight jersey in the spring and fall, and layer it beneath stormproof protection for added thermoregulation in deep winter.
