Rapha Super Lightweight Jersey

Tempting as it may be to go topless on a hot humid day on the road, tradition dictates that riding without a jersey just isn't done (plus, where will you stash your energy bars?). The Super Lightweight jersey from high-end British brand Rapha is made from proprietary fabrics designed to keep you cool, plus it has ventilating mesh side panels. Like all things Rapha it also looks classically cool (as in hip, not in temperature). [$160; Rapha]
