Rab Mens Infinity Alpine Jacket


All about this product



Lighter in weight, with a closer, regular fit, the Rab Men’s Infinity Alpine Jacket excels on alpine style, high energy ascents in winter weather.

The Infinity Alpine Jacket uses two weights of Gore-Tex Infinium Windstopper, and is reinforced on the shoulders, upper body, and outer arms for better protection in rugged terrain. Built using advanced Interstitch construction, it has overhanging baffles with clever internal stitching, ensuring water is channelled away from the body, minimising water ingress. Perfect for when things get chilly, it’s also filled with 800FP RDS down with a Nikwax hydrophobic treatment, maximising the warmth to weight ratio and coping expertly with damp conditions. Other features include a fully adjustable, helmet compatible, down-filled hood with a stiffened peak for increased protection and a two-way YKK VISLON front zip for ease of use with a harness.

Designed to excel on vertical missions, the Infinity Alpine has articulated sleeves for complete mobility, adjustable cuffs for use with gloves and multiple pockets. Extremely lightweight for this level of warmth and protection it can even compress down easily and be packed away in its stuff sack. Highly breathable, windproof and water resistant with a soft feel, this jacket is perfect 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.
