Castelli Flight Long Sleeve Jersey AirSurprisingly light in weight and yet offering excellent cool-weather warmth, the Castelli Flight Long Sleeve Jersey Air is ideally suited for cycling during autumn and spring. Castelli takes their highly functional, partially windproof Nano Flex Light material, used for the back of their renowned Perfetto vest, and uses it to make the Flight Long Sleeve Jersey Air. With its tightly woven structure, it's great at keeping out much of the wind, preventing the heat-sapping effect of windchill.Despite offering more wind protection than a regular long-sleeve woven jersey, it still maintains outstanding breathability too. With no membrane used, moisture can easily escape, while what air does pass through to the inside does a great job of regulating your temperature. Extra comfort also comes via a 3D mesh lining across the front. This delivers quick-wicking performance, ensuring sweat doesn't pool on the skin. During and after harder efforts you’ll find you’ll feel drier and more comfortable thanks to this extra layer. And being drier you’ll remain warmer too.The stretch woven material also gives the jersey a close-to-the-body fit but with plenty of flexibility. In fact, Castelli dub this jersey their Aero Race Jersey for cool conditions. A full-length zipper keeps you in control of ventilation and raw-cut wrist cuffs fit well with your lighter-weight spring/autumn gloves.Features:Materials: 78% Polyester, 22% ElastaneNano Flex Light woven fabric all around partially blocks wind, but lack of a membrane guarantees maximum breathability3D Mesh fabric from Castelli’s base layer range used as front lining for extra warmth and moisture managementYKK® Vislon® zipperRaw-cut wrists integrate easily with glovesClose-to-body fit3 rear pocketsReflective wordmark on back pocketWeight: 190gSuggested Temperature range: 10 to 16 degrees CBuy Castelli Clothing from Chain Reaction Cycles, the World's Largest Online Bike Store.
