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. Other than that change, the Elite Thermal warmers are largely the same; they still provide a greater degree of warmth than Pearl's Lite series of warmers without being as warm or stifling as its winter-specific PRO Leader warmer. In short, they're the classic arm warmers, which puts them in close competition with thermal knit gloves for the title of favorite cool-weather accessory in the Competitive office.
