Womens Phantom 2.5L Jacket

Jump to: Our Verdict / Features / Specifications

A featherweight shell built for speed and sudden weather shift.

Rab says: 

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.

Our Verdict

At just 122g for a Medium, Rab’s Phantom 2.5l Jacket delivers impressive protection in a tiny package. The 7D Pertex Shield fabric is soft, quiet, and breathable enough for high-output days, while still offering solid waterproofing. My favourite feature is the self-stowing hood pocket — the jacket packs down incredibly small and neat, ideal for stashing in a vest or side pocket. The full-length front zip and rear-vented roll-away hood add practicality without bulk, and the fit allows for unrestricted movement without flapping around in the wind. Fantastic for fastpacking, ultralight hiking, or races.
