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 has an extremely high warmth-to-weight ratio which makes it excellent for alpinism and mountaineering. Like all our down products, it’s filled with RDS certified down.

The outer is lightweight yet durable nylon ripstop, with a thin water repellent coating on the inside to protect the down filling (and you) from that spindrift whipping down the gully. 

High fill power goose down makes Phantac incredibly packable and gives you more insulation per gram. It’s treated with Downtek Water Repellent treatment which helps it to recover and retain its loft if it gets damp. The more loft it has, the warmer you’ll be!

Phantac’s active cut makes it comfortable to climb and move in. Medium-sized baffles create a low-bulk shape and prevent the down from migrating round the jacket, whilst articulated arms stop the hem from riding up and letting the cold in when you’re reaching for the next hold. The 2-way zip lets you get to your harness when you throw the Phantac on at a belay. 

When all you really need is a fortress against the cold, Phantac’s helmet compatible hood can be adjusted at the crown and the opening so you can seal out the draughts - the front adjusts from the comfort of your pockets so you don’t have to expose your hands to the cold. Phantac has high external zipped pockets that you can get at when it’s tucked into your harness, 2 internal pockets for stashing gloves or warming rock boots, and an internal pocket for keeping your gadgets warm.   

Whether you’re getting up before sunrise for the summit push or spending a little longer than you’d have liked waiting at a freezing belay, Phantac will give you warmth and comfort at minimal cost to your pack weight.


DownTek-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.

Environmental Considerations

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).
