When the spring sun disappears behind the cloud, you descend in a valley, or it’s just real chilly… The Filoment is an ideal versatile and lightweight addition to your layering system.

Filoment is designed to keep you warm and snug whether moving fast and light or layering up against the cold. An active cut, with longer back and articulated arms, makes it ideal for active use.

Horizontal micro-baffles prevent cold spots caused by down migration, whilst an insulated zip baffle and chin guard shuts out pesky draughts. Soft hand-warmer pockets keep your fingers toasty, the insulated hood warms your noggin, and the zipped chest pocket keeps essentials safe.

We make our down jackets to last with Nikwax Hydrophobic down. Filoment’s durable polyester outer is DWR coated, helping to shed moisture.

With a compact packed-size, Filoment stows away easily and lofts effortlessly.


Nikwax Hydrophobic is a water repellent treatment that makes down less susceptible to humid conditions, staying lofted for longer and prolonging the overall lifespan of your down.


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.

A warmth machine

Picked one of these up in the Spring sale. Have been using a Synoment (ne: Heiko) jacket since early 2015 which has easily been my most used piece of kit due to its versatility. I wanted something warmer with a hood that would be just as versatile. I'm 5'8" with 43" chest and broad shouldered and the size Large fits me perfectly.
It had its first outing in early May. Standing on the summit of Ben Ledi in freezing conditions I was toasty warm with the hoody thrown over my baselayer and windproof. It's much warmer than the Synoment jacket. The hood could possibly do with some simple volume adjustment but its no big deal.
I chose the Reef colour as its bold and bright and it looks great.

Filoment hoody

Ok so I was looking for a micro down jacket , looked at then all and this is far the best , keeps you nice and warm feels and looks great and more important it covers your lower back ! How many jackets of this type are short leaving your lower back exposed ? Brilliant jacket !

Great Down Jacket

fantastic jacket , bought for a bargain £99 - I'm 6'1" with a 46 in chest and the XL fits me perfectly - I also tried/considered the Arcteryx Ceruim LT but that was more than double the price and the Rab Microlight which was £50+ more - very happy so far and am wearing it today in the snow with temperatues below freezing and am nice and toasty - looks great both around town and out on the hills

Lightweight, warm, amazing.

When this arrived, I was a little disappointed as it isn’t as bulky as it looked in the photos. This was supposed to be an upgrade from a decathlon item, and believe me it is.
Wearing it today and the wind is bitingly cold, not had to tighten the toggles up round the hem. Really windproof, and warm. Started to “overheat” with the hood up. Not stood still in this jacket for long, so can’t quote idle heat rating, but walking and moving around this jacket is the right balance I was looking for, comfort.
This is my second bit of kit from Alpkit, and I’m ever falling more in love with their gear!! Keep up the good work.

Alpkit filoment hoody

Very happy customer, wore it for the first time today.. It was 0°c with a wind chill of - 12...absolutely fantastic performance from a very reasonable priced jacket.

Very packable and warm jacket!

Recently purchased this jacket for £99. It packs into a 1L bag and it's very warm! I have been wearing it for a few days at sub-zero temperatures and it's really nice.

Filoment Jacket

Just took delivery of my new Filoment Jacket and chuffed to bits with it. Super warm and extremely light.

Ice ice ready

Was momentarily disappointed by the lightness and thinness of this jacket ( I didn’t think it would be up to much) but I needn’t have worried. Highly packable, I took this to Iceland in January where with temperatures just below freezing and biting wind this jacket kept me lovely and warm. Below freezing you will need a base layer and a micro fleece top or similar underneath but the wind proof nature of this jacket and resistance to light showers meant not needing a waterproof shell. Packs down really small when not needed (I’ve found a three litre mesh bag is great and then squashed down further if needed). Also looks great around town. Quite simply the most versatile jacket I’ve ever owned, now I’m ready for anything.


I bought this jacket and the Rab Microlight in order to compare them. The Rab was slightly better finished but the Alpkit was a better fit under arms and across chest. Great product from a great company. (I kept the Alpkit and returned the Rab)
