More warmth for fewer grams, this is the ultimate ultralight, multi-award winning down jacket for freezing temperatures. Heat reflective tech, featherlight, and packable, it’s a game changer for mountain athletes, outdoor professionals, and fast-moving alpinists.
Our goal was to create an alpine down jacket with our best ever warmth to weight ratio. We set to work combining our advanced heat retaining TILT technology with the lightest, strongest fabrics we could find, and the unbeatable warmth-for-weight of goose down. We also used a combination of baffles to maximise performance. Lightweight stitch through-baffles on the arms and hood give better mobility, and boxwall baffles around the core encourage the down to fully loft maximising heat trapping. The baffles are offset, which distributes the down evenly around the core and reduces the chance of any cold spots.
After extensive R&D we found that positioning the layer of TILT as close to the body as possible maximised heat retention. This heat reflective layer gives the Mythic Ultra Jacket a noticeable boost in thermal efficiency, welcome warmth on frigid belays and frozen summits. To keep weight at a minimum we used an ultralight 10D outer which is 100% recycled. This Pertex® Quantum fabric with built-in ripstop is strong, durable, weather protective and feels soft to the touch.
Designed for use by alpinists and mountaineers it has a helmet compatible hood, two-way front zip for use with a harness, and fine-tuned articulation through the sleeves for climbing. All zips, adjusters and the stuff sack have been designed to be lightweight and low bulk.
Scooping up both an ISPO Award 2022 and GearJunkie’s “Best in Show” celebrating future-leading technology and construction, the Mythic Ultra is a game changer for mountain athletes who count every gram.

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.
