Description:

This jacket is now also available in custom sizesSpecify Body Width, Body Length, and Arm Length independently to order a made-to-measure down jacket. This tailor-made service can cope with sizes from XXXS to XXXL and is ideal if your chest/waist to height and/or arm ratios differ from standard, ready-to-wear patterns. 


Facing an early morning start, a cold wind high up, even an unexpected bivvy. Whenever you're going to need extra warmth on your peak, it doesn't come much lighter than the Alpine Ultra. It's lighter than fleece, much warmer, packs a lot smaller and has a 100% windproof outer too.

Super-light fabrics and our exceptional 950 down provide the superb warmth/weight performance. Chest pockets and a large (optional) hood allow harness and helmet use. A fleece collar? That's in there too.

Note: The optional hood needs to be ordered at the same time as the jacket.

Please note: If you order a custom-sized version of this jacket it will take longer (approximately 45 days) to be manufactured ready for dispatch. Custom-sized versions of this jacket are not returnable and customer loyalty discount cannot be applied.

Water-resistant Drishell outer fabric (weight: 54 gsm)

Ripstop nylon with an ultralight coating: achieves total windblock, along with high breathability and superior water resistance. Superbly efficient for a very light overall fabric weight.


Superlight MX fabric (weight: 32 gsm)

A mini-ripstop nylon with excellent tear strength, MX is the pick of the superfine 15 denier downproof materials. We have tested lighter fabrics, but most have had significant drawbacks, while our confidence in MX is based on several years of extensive use in both our ultralight and our high mountain gear.


950 fillpower down

A newcomer to our range. European goose of rare quality. A high value alternative at the top levels of performance. More on our down insulation.

"Alpine Ultra jacket was definitely the "go to" piece of kit for the whole expedition. Quick on, quick off, stuff it in the pack, clip it to an anchor whilst you sort gear. Drishell is durable enough for arm rappels on fixed ropes and definitely proofed enough for high mountain conditions."
Ben Kane

"Packs to nothing."
Petesy (a.k.a. Peter Macfarlane).

"It's the perfect alpine downie - 330g and rated to -10 degrees - it blows the competition out of the water. Whilst the weight is awesome, you also get a tiny packed size out of it meaning that your down jacket won't eat up half your backpack space so you can go with a small backpack (20L) and keep a light and fast rhythm to your climbing."
Jon Griffith.

"I used the Alpine Ultra Jacket as a belay jacket and emergency outer layer in the Indian Himalaya - I found it to be excellent. It's lighter and packs down smaller than any comparable jacket, and its warmth to weight ratio is second to none. There is no other jacket that I would've preferred to have with me."
Virgil Scott - Imperial College Reru Valley Expedition (Zanskar Himalaya, India).

"Thank you for the fantastic equipment. Everything (including the Alpine Ultra Jacket) was above and beyond what was required and fended off the elements perfectly."
Graham B., on a trip to Aconcagua.
