Assos Thermo Booster P1 Spring Fall base layer

A versatile, packable, and ultrabreathable thermal layer for high-intensity riding, updated with pockets for use as a jersey for cool conditions or as a midlayer for additional core protection in the coldest, most challenging conditions. 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.

Skuba
Skuba is a new textile with a circular knit structure and a soft, carbon-brushed inner face that creates low-volume loft for heat-trapping insulation. It’s also breathable enough to maintain a dry microclimate during full-gas efforts.

Construction
The AEPD 11 racingFit is a second-skin, aerodynamic silhouette designed with WorldTour feedback to envelope the body in 360-degree compression and stability. It also makes for low-volume layering, unlocking three-season versatility.

StruzzoKragen
A collar of lighter, soft insulation with a comfort fit. Actively modulates the personal microclimate without requiring unzipping and exposing the throat to cold air.

Twin Pocket
A pair of rear pockets add storage options for standalone versatility as a thermal jersey in cool conditions.

Raw Cut
Sleeve and waist are raw cut, eliminating transitional ridges for low-volume, frictionless layering with shells, jackets, and gloves.
