Similar to Sportful's traditional warmers, the No Rain version features an anatomic cut and smooth, single seam construction to keep your arms warm and comfortable. But these received added protection by integrating an effective water repellent finish. The warmers were made Sportful's No Rain material, which features its nanotech water repellent treatment. So, in addition to being highly elastic and providing a light layer of warmth, they also shed water from the surface. A light silicone treatment provides a secure connection, and reflective logos boost your visibility in low light conditions. The Sportful No Rain Arm Warmers are available in sizes Small to X Large and in the colors Black, Red, and White.
