PEARL iZUMi Elite Thermal Arm Warmer Black, XL

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, and they've been updated with Pearl's PI Dry DWR treatment, which helps them shed water instead of turning into sodden arm socks on spring rides that feature some April showers.
