Castelli Pro Seamless 2 Arm Warmers Description:
When Castelli set out to make a better arm warmer, they leveraged their relationship with top pro teams and their extensive knowledge of materials to craft the incredible Pro Seamless 2 Arm Warmers. It took them longer than anticipated, but they found the right material combination to create the blend of stretchiness, moisture management, and temperature regulation that matched exactly what the Castelli product team was looking for. The result? A lightweight set of arm warmers that, when a rider pulls them on, they simply disappear and provide the right balance of warmth and breathability to maintain comfort even if the temps climb a bit. Finally, the lightweight Castelli Pro Seamless 2 Arm Warmers have a compact size when folded up so they easily can be tucked into a jersey, tight, or pant pocket until they are needed again.
Features:
- Extremely warm for how light these arm warmers are with enough breathability to prevent overheating if the temperatures climb mid-ride
- Fully seamless construction prevents cold air from seeping in through a weak spot and reduces irritation on the skin
- Unique polyester/nylon/Lycra blend has great moisture management and just the right amount of stretch so it hardly feels like anything is covering the arms
- Lightweight and takes up very little space in a pocket when folded up
