Castelli Pro Seamless Cycling Knee Warmers - Black

The Castelli Pro Seamless Knee Warmers are specialised cycling accessories designed to provide targeted warmth and protection for cyclists' knees during transitional weather conditions. Developed in collaboration with World Tour professional riders, they address the common problem of damp, uncomfortable kit that can hinder performance and add unnecessary weight. These warmers are specifically engineered for those in-between days when full-length tights would be too warm but bare knees would be too cold. The warmers feature a seamless construction that eliminates potential chafing points while minimising overall weight. They utilise a unique fabric blend of 78% polyester, 15% nylon, and 7% Lycra, which was developed over an extended period to optimise performance. This composition provides excellent breathability while resisting moisture retention better than traditional nylon/Lycra blends. The high-stretch material ensures full freedom of movement during pedalling, and when removed, they fold up exceptionally small for convenient storage in jersey pockets. These knee warmers are best suited for road cyclists and enthusiasts who ride in changeable spring and autumn conditions. With a recommended temperature comfort range of 10-20°C (50-68°F), they offer practical warmth without causing overheating during more intense efforts. The unisex design and lightweight construction (approximately 52g per pair) make them a versatile addition to any cyclist's wardrobe for extending comfortable riding seasons in the UK climate.
