Designed to keep you dry in cool weather. The Prosecco Tech Long Sleeve base layer features a body mapping construction to provide the best wicking and correct levels of insulation right where you need it.   The main body is made from a rib knit fabric with Prosecco hydrophilic treatment. The ribbing helps trap air against your skin for optimum temperature regulation, while the hydrophilic treatment helps whip water away keeping you dry even when the efforts intensify. For even insulation across your upper body the Prosecco Tech uses PrimaLoft® panels at the waist and back. This thinner material means you don’t overheat where you have multiple layers from your bibtights and jersey. A crew neck fits neatly under short-collared jerseys.   Features 100% polyester proprietary stretch rib knit fabric for main body. Prosecco hydrophilic treatment for maximum wicking. PrimaLoft® panels at waist and back where bibshort covers upper body for even insulation. Crew neck closure to fit under short-collared jerseys. 10˚ – 20˚C / 50˚ – 68˚F. Weight: 114g (Large).
