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.
