Pro Seamless Arm Warmer

For those shoulder season temperatures, when committing to a full long sleeve feels a bit like overkill, Castelli's Pro Seamless Arm Warmers let you more easily control your temperature as you heat up throughout the ride or race. Through years of development with Castelli's Pro teams, they crafted these warmers with a blend of polyester, nylon, and Lycra fibers for the perfect balance of warmth without weight or bulk. They provide enough warmth to keep your mind of the chilly temperatures, while the breathability of the fabric keeps you from overheating. When things heat up, the warmers are lightweight and packable to fit comfortably in a jersey pocket for the rest of the ride.

• Midweight arm warmers to keep you riding all year long
• Pro-level fabrics and fit offer superb comfort and moisture-wicking
• Packable size fits easily in jersey pocket when the day heats up
