Castelli Prologo 7 Long Sleeve JerseyThe Castelli Prologo 7 Long Sleeve Jersey has its focus on providing sun protection on warmer days of cycling. With its lightweight and breathable fabrics offering excellent comfort in the warm, it’s an alternative to slathering on suncream.With a body constructed in lightweight and breathable micro-piqué polyester, the Prologo 7 Long Sleeve Jersey is perfectly suited to the warmth of summer. As the temperatures rise or harder efforts are required, it’s quick to wick away sweat. It also offers UPF50 (Ultraviolet Protection Factor), blocking 98% of UV rays, protecting you from sunburn, while also offering plenty of airflow so you don’t overheat. Sleeves are also made in a sun-protecting material too. The Velocity Rev2 fabric gives you a UPF of 30, blocking 97% of UV rays. And again being lightweight and stretchy like the body, you’ll enjoy excellent comfort and mobility alongside quick moisture management. While excelling in summer, with a heavier weight base layer it’s also great for cooler spring and autumn days. And with a smooth sliding full-length front zip, it’s easy to regulate airflow and body temperature. 3 rear pockets are there to load up with your essentials, the drop-pocket design putting them in just the right place too.Features:Materials: 100% PolyesterMicro-piqué polyester knit on the body for great moisture managementUPF 50 rating to the bodyVelocity Rev2 fabric on the sleeves with UPF 30 sun protectionFull-length YKK® Vislon® zipper with neck protector3 rear pockets with drop-pocket design for an optimal pocket placementSilicone gripper elastic at waistReflective details on both sides of pocketSuggested Temperature range: 14 to 32 degrees CBuy Castelli Clothing from Chain Reaction Cycles, the World’s Largest Online Bike Store.
