If you could choose just one shell to always have by your side, this would be it. Versatile like no other, this jacket can easily convert into a vest mid-ride, or even stuff into itself and, using an integrated strap, be stored directly on your bike. Featuring a semi-form fit, it's comfortable on and off the bike, and has two convenient hand pockets for casual use. A thick, easy-to-grab zipper pull is nice when you need to quickly dump heat on a climb, and a mesh upper back allows additional ventilation. Bring it Mother Nature, this jacket is ready.
