From the relentless force of a Scottish winter to the unexpected onset of an alpine storm, this uncompromising waterproof jacket is built to weather anything the mountains put in your path. Armed with 40D, 3-layer Pertex® Shield, it offers guides and dedicated alpinists the day-in day-out durability and unyielding protection they need on weather-beaten climbs. The articulated, unrestrictive sleeves allow you to reach upwards and swing ice tools, while the ascent-specific features help streamline your time on the rockface. Reassuringly tough and protective, the Firewall Guide Jacket gives you the confidence to tackle committing routes in any conditions.
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.
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.
