Before we head out on a mild-to-cold-weather ride, we zip up the ASSOS Fall Long-Sleeve ThermoBooster for added warmth during our high-intensity training. The new Skuba thermal textile features a soft, carbon-brushed inner face and a circular knit structure, which creates a low-volume loft that traps heat inside while maintaining optimal breathability to keep us dry when pushing out max watts. We love how easy the AEPD 11 racingFit construction of this zip-up baselayer is to layer both over or under a jersey with its second-skin, aerodynamic silhouette, and the collar of soft struzzoKragen insulation that keeps the temperature of our throat area regulated.
