With its technical Atmos fabrics and high-loft insulation, the superlight Prosar Jacket is a high performance micro-baffle down jacket with additional weather protection, making it extremely versatile for use as a mid or outer layer.
Extremely warm and packable, the lightweight 10D Atmos shell and lining allows the ethically-sourced RDS-certified 800FP hydrophobic European goose down to loft fast, giving instant warmth with minimal weight. It also features zoned stitch-through construction for refined styling and bulk-free mobility during active mountain use. The tightly woven polyamide yarns of the Atmos fabric outer make it highly wind and water resistant and the jacket also includes a down-filled hood, low-profile elasticated cuffs, a pair of zipped hand pockets and a stuff sack for convenience on the move.
With a weight of just 371g, alongside zoned midi and nano baffles for improved down distribution, the Prosar Jacket provides excellent warmth and weather resistance for both alpine use and everyday insulation.

The Rab story began in 1981 in the attic of a small, terraced house in Sheffield where Rab Carrington made the first sleeping bag to bear his name. Hand-stitched and devised with his own ingenious eye, Rab's experience from years spent in the mountains was apparent in his designs, and soon there was popular demand from Rab's friends and the growing local climbing community. Now, decades later, those honest, hard-wearing designs can be found all over the world; wherever adventurous individuals face up to the elements. From Himalayan peaks to cold, crisp evenings around a camp fire. This began as the brand's story, but it also belongs to those who've loved and cared for each and every one of our products. Who've made them their companions on long trips and expeditions.
