Description

Filoment is our most packable insulated jacket with an excellent warmth to weight ratio and made using 100% recycled fabrics and fill. It’s designed for active use, so it doesn’t get in the way on the technical bits and is versatile enough to fit into your layering system.

  • 100% recyled nylon fabric and 100% RCS 100-certified recycled down
  • Lightweight fill and fabrics are highly packable
  • 630FP down provides excellent warmth to weight ratio

The outer made is from light yet durable nylon fabric that's 100% recycled and treated with a PFC-free durable water repellent to keep your down protected from moisture without using nasty chemicals. The 630 fill power down provides an excellent warmth to weight ratio and is fully recycled (RCS 100 certified), to re-use down that would otherwise go into landfill.

Narrow micro baffles give the Filoment an active, slim fit. It has a dropped, adjustable hem at the back and articulated arms that stop it from riding up when you’re reaching for that next hold or bending over to fit your snowshoes. The insulated zip baffle, chin guard and under-helmet hood keeps you well-defended against the cold.

Filoment also has two zipped hand warmer pockets, internal dump pockets and an external chest pocket for your phone, keys, and other valuables.

Incredibly packable and light, Filoment is a staff favourite. We’ve worn ours on evenings around camp, Alpine starts, and even as part of our sleep systems on ambitiously minimalist mountain marathons.

Care & Environmental Advice

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.

Environmental considerations

PFC-Free DWRs
As part of our continuing effort to remove long-chain flurocarbons from our outer garments, we’re now using PFC-free Durable Water Repellent (DWR) treatments across our down range. C0 DWRs are non-toxic and don't build up in the environment, causing significantly less environmental damage.

RCS 100 Certified Reycled Down
For the Filoment we've used recycled down to reduce our usage of 'virgin' down and to re-use valuable materials that would otherwise be sent to landfill. The Recycled Claim Standard (RCS) is a standard to track materials through supply chains.The RCS 100 stamp ensures that at least 95% of the material is from recycled sources.

Fit Guide
Tight Slim Regular Relaxed
Close fitting designed to conform to your body shape. Slim and slightly contoured but not form fitting. A comfortable fit that's not too tight, nor too loose. A looser fit with a bit more space but not too baggy.

Kudos
Grough reviews the Filoment jacket
"Warmth was good and the Alpkit jacket resisted snow and sleet showers quite well. The jacket also blocked the wind well. Overall, the jacket was comfortable and didn’t restrict movement.

The Filoment represents good value for money for a down jacket and has good green credentials. It’s lightweight but still provides a good level of warmth."
