Castelli Pro Seamless 2 Arm Warmer

Blacks

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.Key FeaturesMid-weight seamless warmer developed with World Tour team ridersWarm without causing overheatingUnique polyester, nylon, Lycra blend (78%, 15%, 7%)Folds up extra smallTemperature comfort range of 10˚C – 20˚CWeight 64g (Pair - approx)
