DESCRIPTION
The Castelli PRO Seamless 2 Arm Warmers are born from direct collaboration with the UCI WorldTour team Quick-Step Alpha Vinyl, with the precise goal of redefining the standard for seamless cycling arm warmers. The starting point was the material: while most arm warmers on the market use a classic nylon/Lycra® blend that tends to retain moisture, Castelli chose a different textile construction, designed to better manage the microclimate during prolonged physical exertion.
Construction and thermal comfort
The seamless technology completely eliminates seams along the body of the arm warmer, reducing pressure points and the risk of skin irritation even during the longest rides. The snug fit ensures no creases that could interfere with pedaling or create friction under the jersey sleeve. The construction profile is calibrated to cover a wide temperature range, making them suitable for both cooler morning rides and transitional seasonal days.
Key features
- Completely seamless construction for maximum skin comfort
- Fabric developed for active moisture management, superior to traditional nylon/Lycra® materials
- Compressive and anatomical fit without a constricting effect
- Developed in collaboration with WorldTour professional athletes
- Suitable for a wide thermal range for use in spring and autumn
The result is an arm warmer that feels almost like a second skin: no excess fabric, no sweat accumulation areas, and easy to put on and take off, even during quick stops during a ride.
