Bubble wrap bed? Check! Some form of Franken-tent? Check! For some adventures, we find all manner of bizarre hacks to keep the weight down.

Filoment vest provides the warmth of the Filoment jacket, targeted around your core. It leaves your arms unrestricted for moving quickly, packs down incredibly small, and layers well over a base layer or under a shell. That’s why it’s our first choice for any situation where a light, compact pack-size and freedom of movement are the top priority.

Narrow baffles give the Filoment vest a slim, active fit. It has a slightly dropped, adjustable hem at the back for good coverage and lycra bound armholes for freedom of movement. 

Vests let you dump more heat than jackets. For a boost of warmth, you can bury your hands in the hand warmer pockets whilst the external zipped chest pocket takes care of your valuables. The zip baffle and chin guard keep draughts from finding their way in.

The outer fabric is a light yet durable 40gsm nylon with a PFC-free, C0 DWR coating, well equipped to handle the demands of active use as well as being non-toxic to the environment. The responsibly sourced 650FP down fill gives an excellent weight ratio. It’s also hydrophobic, so it retains loft in damp conditions and recovers better too.

Environmental Considerations


As part of our continuing effort to remove long-chain flurocarbons from our outer garments, we’re now using C0 Durable Water Repellent (DWR) treatments across our down range. Despite the slight impact on performance when compared to C6 DWRs, C0 DWRs are non-toxic and completely PFC-free, causing significantly less environmental damage. 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.


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 hydrophobic 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.

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. Read our Down Wash Guide for advice on washing your down jacket, or alternatively let us take care of it for you.
