Castelli Pro Seamless Knee Warmer Leg Warmers – Black | Thermal, Compact, Seamless
The Castelli Pro Seamless Knee Warmer leg warmers are the ideal accessory for cycling outings between 10°C and 20°C, offering a perfect combination of thermal protection, breathability, and absolute comfort. Thanks to the seamless construction, these leg warmers wrap the knee like a second skin, eliminating any points of friction or chafing.
The fabric is a technical blend composed of 78% polyester, 15% nylon, and 7% Lycra®, which ensures elasticity, softness, and thermal insulation. The medium weight structure provides excellent protection against the cold while remaining highly breathable to prevent overheating during pedaling.
With a weight of only 75 grams, the Pro Seamless Knee Warmers also stand out for their ease of transport: they fold easily, take up very little space, and are always ready to use in the back pockets of your jersey or in a saddlebag.
