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

People wearing and using Rab gear are hanging on a snow mountain and enjoying interesting snow views and a drink.

Rab specialise in making rugged, high-performance mountain clothing and equipment. Created to give you ultimate freedom, protection and comfort, we use cutting edge materials as well as time-tested ones such as premium quality European down.  Nothing fancy or over-engineered – just honest, hard-working pieces that you’d rather repair than replace. 


More than thirty years since our founding, we continue to find inspiration in the untamed spirit of the mountains where we climb, the friendships we forge on the peak and our enduring mission: to awaken the climber in everyone and equip them for the ascent.
