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 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. 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.
How to measure.
Chest: Measure the full circumference of your chest just below your armpits.
Waist: Find the top of your hip and measure the full circumference around your body.
Arm length: Measure horizontally from the centre of your back, across the shoulder, over a naturally bent elbow and down to the wrist fold.
Hips: Measure around the widest part of your hip area.
While all our garments are sized to these measurements, you will find that the cut on jackets designed for use in more extreme environments will be slightly more generous in the expectation that these designs will be used with additional/thicker midlayers. If you plan on using a jacket like this with fewer layers beneath it, please keep this in mind when selecting your size.
All garments are designed and fitted to suit their intended end use. See below for a general description of our fit categories:
Regular: Neither slim nor loose. Regular fit items are the perfect balance of form fit and ease of movement.
Slim: A streamlined silhouette. Cut trim following the contours of the body. Expertly placed articulation of seams and the use of stretch fabric ensure maximum freedom of movement in these close-fitting items.
Relaxed: Our more generous fit. Cut loosely through the body allowing for ease of movement and additional layering.
Expedition: Designed specifically to accommodate the layering system and equipment required for high altitude and polar expeditions.
