This highly protective down jacket has evolved from the definitive high mountain Infinity Jacket. Lighter in weight, with a closer, regular fit, it excels on alpine style, high energy ascents in winter weather. The Infinity Alpine uses two weights of GORE-TEX INFINIUM™ WINDSTOPPER®. The outer is reinforced on the shoulders, upper body, and outer arms for better protection in rugged terrain. Highly breathable, windproof and water resistant with a soft feel, this jacket is perfect for winter climbing and mountaineering. Built using advanced Interstitch construction, the Infinity Alpine has overhanging baffles with clever internal stitching, ensuring water is channelled away from the body, minimising water ingress. Filled with 800FP RDS down with a Nikwax hydrophobic treatment, the Infinity Alpine maximises the warmth to weight ratio and copes with damp conditions. Extremely lightweight for this level of warmth and protection it can compress down easily and be packed away in its stuff sack. It has 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.



Baffle Technology

These baffles are built differently. To increase weather protection, we’ve engineered clever internal seams with every baffle overhanging the one below it. Water is encouraged to simply shed off the jacket rather than creeping through the seams, thanks to the wonders of gravity. In especially wild weather, any moisture is channelled away from the seams because the fabric between baffles is held in a vertical fold. This greatly reduces the chances of water ingress, keeping you warm and dry.
