The Winter is the warmest Assos long sleeve base layer. It accomplishes this by supplementing the SPC.07 fabric with the same warm, thick material proven to be so successful in Assos' previous generation frigid-weather base layer -- the Powerstatic Plus. The Winter has the same zippered, high-neck construction as the earlyWinter base layer. This neckline, plus the arm pits and backs of arms are made solely of SPC.07. The rest of the Winter is made from heavier, more-insulating fabric.

Assos suggests that you use the Winter Long Sleeve in conjunction with their airJack or fuguJack jackets, depending on the temperature. Assos recommends the Winter for temperatures ranging from 32-46 degrees. Available in sizes Small-TIR, in Black only.
