Castelli Pro Seamless 2 Arm Warmers Black 24A

The Castelli Pro Seamless Arm Warmers were developed in collaboration with World Tour riders with the aim of creating a better warmer design for those in-between weather days.

Damp kit is often uncomfortable can hinder your performance and adds unnecessary weight. Many warmers use a nylon/Lycra® blend that tends to hold moisture but Castelli resolved this issue by introducing polyester into the unique fabric used for the Pro Seamless Warmer range.

It took Castelli a year longer than expected to perfect the material composition but their breathability excellent warmth-to-weight ratio and comfort have quickly made them a pro rider favourite. When the warmers are on the high stretch fabric means you hardly feel them and when you take them off they occupy a fraction of the space that normal warmers would take up in your pockets.
