If you're covering year-round riding with a single baselayer, chances are you've been uncomfortably cold or warm at some point during the calendar. Assos makes clothing tuned to meet the demands of intense training during each season. And the Assosories Summer/Fall Short-Sleeve Skin Layer is constructed to take the bite out of the crisp air of spring and autumn without overheating you when you get up on the pedals. A close-fitting, next-to-skin cut ensures the layer can effectively wick sweat away to keep you comfortable as well as not bunch under your jerseys or thermal jackets. Assos uses soft synthetic fabrics for warmth with a bit of carbon fiber integrated for this performance baselayer's durability.
