The Phantom Jacket is one of the lightest waterproof shells available, offering stashable, barely-there protection for ultra running, mountain races, and long-distance thru-hiking. Features have been stripped back to those you really need without compromising on utility, from the handy full-length zip to the ventilated roll-away hood. The jacket packs into its hood when rainclouds clear, creating a palm-size pack size that effortlessly stashes away into your backpack or running vest, ready for a sudden shower.
