Cold weather comfort that won't slow you down.

Windproof outer & hydrophobic fill

The Rab Proton Jacket is a light, durable and highly compressible down jacket with a lot of thought behind its uncomplicated design.

It's made using Atmos ripstop fabric filled with 800FP hydrophobic goose down so it will keep you warm in very cold and damp conditions. The stitch-through zoned construction keeps the down fill in place and at its most effective.

Cut to Rab's 'Slim fit', it's tailored to work underneath a waterproof shell without being restrictive.

• Atmos™ ripstop nylon outer fabric & lining

Atmos fabric is lightweight, durable and very tightly woven. It's fast drying, very packable and water-resistant. In addition, it's windproof, fibreproof and downproof.
