Castelli Arm Warmer Pro Seamless 2 Black

These arm warmers offer a wide temperature range and high - stretch seamless comfort, making them our most adaptable option. In collaboration with Ineos Grenadiers, we aimed to create a superior seamless arm warmer. While many on the market use a nylon/Lycra® blend that retains moisture, our arm warmers use a polyester yarn for better moisture management. Working with polyester was a challenge in achieving the right stretch, return, and manufacturing consistency, but it was worth the extra year. Pro riders love these warmers because they're incredibly light and offer great warmth for their weight. You won't overheat even in milder conditions. They're so stretchy you barely notice them on, and they fold up to take up very little space in your pocket. Product features include a mid - weight seamless design, excellent warmth without overheating, a unique 78% polyester/15% nylon/7% Lycra® blend, fully seamless construction, extra - small fold - up size, a weight of 59gm, and a temperature range of 10°C - 20°C / 50°F - 98°F.

Using these arm warmers is easy. Just stretch them over your arms and adjust as needed. They're great for rides in temperatures between 10°C and 20°C (50°F - 98°F). Don't worry about overheating as they're designed to keep you at a comfortable temperature. When not in use, you can fold them up really small and store them in your pocket. For maintenance, it's best to follow the washing instructions on the label. Usually, a gentle machine wash with mild detergent and air - drying is a good idea. Avoid using harsh chemicals or high - heat drying as this might damage the unique fabric blend.
