Men's Packable Down JacketWhether youre waiting at the meetup spot or suiting up for the descent, our Mens Packable Down Jacket is built for the coldest parts of the ride. ALLIED Feather + Down Fill and PrimaLoft Bio combine to create lightweight insulation that keeps you warm when you need it to but packs small when its time to stow the cycling jacket in a jersey pocket. To help block the chill when temperatures drop, a roomy hood fits over your helmet to lock in the heat.
