If you’re going the distance with that Alpine start, you may as well be wearing a jacket designed to go the distance too…

Phantac is a warm and lightweight fortress against the cold, made for mountaineering and alpinism. It works well layered under the Definition waterproof shell.

It has an active cut that makes it comfortable to climb in. Medium baffles create a low-bulk shape with articulated arms to stop the hem from riding up when you reach for the next hold. You can adjust the hem from the comfort of your pockets, which avoids sacrificing your hands for a snug fit. The 2 way zip makes it comfortable worn over a harness.

Phantac’s features are designed to work with your climbing gear. The adjustable hood is helmet compatible and the external pockets sit out of the way of your harness. On the inside you’ve also got 2 stash pockets for gloves or rock shoes and a zipped pocket that keeps your phone or head torch warm. 

High fill power goose down gives the Phantac an excellent warmth-to-weight ratio. It’s hydrophobic, so it retains thermal qualities when wet.

The nylon ripstop outer is light yet tough, with a water repellent coating to protect the down (and you) from that spindrift whipping down the gully. 

Whether you’re up early for the summit push or at a belay for longer the you’d have liked, Phantac gives you warmth and protection at minimal cost to your pack weight.

Designer Notes

The Phantac has the best warmth-to-weight ratio of any of our down jackets, but there’s another hidden benefit that makes it most suitable for mountaineers. The outer fabric has a light PU coating on the inside, which gives you extra protection against moisture – perfect for shrugging off spindrift. - Ronnie

Environmental Considerations

DOWNTEK WATER REPELLENT DOWNDownTek-treated down absorbs less water than untreated down. This means it retains its loft better in damp or humid conditions, dries quicker, and recovers better too, keeping you warmer in damp environments than untreated down. DownTek is environmentally safe - Bluesign approved, PFC, PFOA, and PFOS free – and uses only RDS certified down sources. Remember, it’s better not to get your down wet – even water repellent down is no substitute for a waterproof shell!


We use only RDS certified down; all our down is audited by a third party to ensure that it comes from birds who are not live-plucked, force-fed, or mistreated. That’s good know.


The chemical finish that keeps water beading off your jacket has changed. 
As with all garments from responsible outdoor brands, our DWR treated garments meet international environmental standards and require occasional washing with a technical wash to maintain their high breathability. 
This wasn’t always the case. Years ago, garments were treated with chemicals that had toxic by-products that lingered in the environment for generations. Those old chemicals needed little maintenance, whereas modern waterproofs need regular washing. 
We fully support this change. In fact, we quite like the idea of taking time to look after our kit so that it lasts a long time. 
We are committed to reducing the environmental impact of all our products –in fact it’s in our DNA: we can’t imagine ever doing anything else. We always review the materials we use, manufacturing methods and our own consumption of resources. We do the research, make informed decisions, and choose the best option available to us.

Product Care Information

You can and should wash this garment, most active outdoor folk do this once or twice a year.

Washing and re-waterproofing flushes out the dirt and oils that have accumulated so that it puffs up nicely and works better in damp conditions

Don’t panic! Down is surprisingly durable and washing is not an onerous task. You can wash it in a front loading washing machine with our detailed instructions (see the FAQs).

Very warm, comfortable jacket.

I bought an XL in the sale and when it arrived thought it was too big. I wore it carefully around the flat with the labels on for a while, then felt confident enough to go out with it - and never looked back!
It actually fits very well. This is my first jacket of this kind so while it felt big, it was snug around the armpits, waist and sleeves. It works best with a layer or two underneath, as wind can still get in under the waistband unless you do it up very tightly. The elasticated sleeves are great, though, and the hood is cavernous.
My only criticisms are that it's a little short in the body and the pockets are an odd shape. I find I can't really rest my hands in the pockets, they're very narrow and deep.
But these are minor niggles. It's a great jacket, and packs down nicely into my saddle pack. I'm going to be using this jacket as my main warmth provider on a year-long bikepacking trip around Europe. I feel I've made the right choice with this! Thanks!

Warm with ample hood yet trim cut so could even fit inside a shell. Sized about right for medium with 32 waist and 38 chest

Great very warm

This is a well made, well thought through jacket it's got great pockets and a really good hood. My only concern is it's a little short at the front but this is very helpful when using with a harness. Used it in Scotland last year was great.

Walk Highlands Review the Phantac

It’s a really excellent and practical down jacket at a very reasonable price.


Walk Highlands December 2018 - Paul Webster

Good Value

Phantac Gets ‘Good Value’ from UKC/UKH

A good all-rounder, with a decent quantity of mid-quality down fill, the Phantac seems sufficient for most UK winter situations, while remaining light enough for use in spring and autumn.
