Bontrager's Convertible WSD Windshell seals out the elements with an ultralight microfiber fabric that's windproof and water resistant. Zip-off sleeves let this versatile piece easily adapt to wildly changing conditions so you stay comfy even when the weather's in a foul mood. Four pockets let you carry essentials and give you a place to stow the sleeves when the Windshell's in vest mode. And, you'll love the cycling-specific cut and the reflective accents for safety.
