During spring and fall, your windproof winter jacket is often overkill, yet your summer jersey isn't insulated enough for these chilly transitional months. The Pearl Izumi Elite Thermal Arm Warmers are designed for just this purpose, providing a greater degree of warmth than Pearl's standard Thermal Lite series of warmers, without being as warm as its winter specific P. R. O. Barrier warmer. Utilizing Pearl's Elite Thermal Fleece panels, these arm warmers assist in wicking moisture off your skin for superior comfort when you're riding hard. These fleece panels keep your arms toasty warm through cool to chilly conditions. Advanced anatomic shaping provides a left and right arm specific fit. Other key features include a plush, wide elastic binding with silicone grip for a secure, stay put fit, as well as reflective elements for boosted visibility on the road.
