Rab Mens Infinity Alpine Jacket


All about this product



The Rab Men’s Infinity Alpine Jacket is a top performer on alpine-style, high-energy winter ascents, offering a lighter weight and a snug, regular fit. Crafted with precision, it utilizes two weights of Gore-Tex Infinium Windstopper and is strategically reinforced on the shoulders, upper body, and outer arms to enhance protection in rugged terrain. The advanced Interstitch construction incorporates overhanging baffles with clever internal stitching, redirecting water away from the body to minimise ingress. Filled with 800FP RDS down treated with Nikwax hydrophobic technology, the jacket excels in maintaining a high warmth-to-weight ratio and adeptly handles damp conditions.


Additional features include a fully adjustable, helmet-compatible, down-filled hood with a stiffened peak for enhanced protection, and a two-way YKK VISLON front zip for easy use with a harness. Tailored for vertical missions, the Infinity Alpine boasts articulated sleeves for complete mobility, adjustable cuffs for glove compatibility, and multiple pockets. With its high breathability, windproof and water-resistant properties, and a soft feel, this jacket is an ideal companion for winter climbing and mountaineering.

About this brand


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.
