Built for reaching frost shattered summits in the biting cold, this ultralight down jacket offers alpinists and mountaineers impressive warmth and mobility.
The Alpine Jacket in our Mythic series is designed for those moving fast and light. For those who want an extremely warm down jacket you can climb in, stash easily, and throw on when you need an instant boost of heat. Shaving grams wherever possible it has lightweight, low bulk, stitch-through construction to stabilise the down while allowing excellent breathability. Squares around the core maximise warmth while regular baffles on the sleeves improve mobility. Pre curved and articulated the sleeves have also been designed to allow easy arm lift, movement, and articulation for climbing.
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. Slim-fitting and low bulk, the jacket layers easily under a shell and helps manage moisture through your gear, perfect for moving at pace. When a balance of weight, mobility and warmth are critical for success, the Mythic Alpine Jacket is the ultimate choice.

Fluorocarbon-Free Product
This product no longer contains fluorocarbons. Whether that’s in a DWR, on the zips, the threads or in the fabric. Find out more about how we’re cutting fluorocarbons from our gear.
Pertex® Quantum
A soft, lightweight, windproof fabric that encourages insulation to fully loft. Highly packable and protective, it's ideal for mountain activities.
Fill Power - 900
Fill power is all about down quality, not quantity. Find out more about what fill power means for you when you're out in the mountains in cold conditions.
What is hydrophobic down?
We finish all our down with a hydrophobic treatment that enables it to retain its loft in damp conditions, so that your gear dries fast and stays warm. Find out how it works.
*With the exception of our 1000FP down.
RDS Certified Down
The Responsible Down Standard independently certifies down against animal welfare requirements and tracks it from the source to the final product.
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.
