Featherlight insurance for that inopportune time when the weather takes a turn for the worse, the Pearl Izumi Optik jacket has you covered for cycling in questionable weather. The 100% polyester Optik fabric is highly breathable in addition to its effective water and wind shedding abilities, providing excellent moisture transport even when exerting at a high level. Reflective logos on the front and back provide a measure of security when moving with traffic in weak visibility, and a zippered rear stash pocket keeps snacks and other supplies within easy reach. The Pearl Izumi Optik men's cycling jacket is highly compressible and weighs just over 3 ounces, so the price of bringing it along is minimal at most.
