The sun is slipping below the mountain horizon as you start up the last pitch of the day, or maybe you’re trying to keep your load as light and compact as possible as you race across the dragon’s back.
Filoment is our most packable insulated jacket. 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.
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.
The outer fabric is a light yet durable 40gsm nylon with a DWR coating, well equipped to handle the demands of active use. 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.
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.
DOWNTEK WATER REPELLENT DOWN
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!
RESPONSIBLE DOWN STANDARD
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 to know.

I don't like it, I LOVE it!
Love this coat and its prompt arrival. The chilli colour is great and the fit is perfect. I have spent years looking for the perfect fit and Alpkit get it right every time.
I wanted a down jacket that wasn't rustly(!) or too puffy. I also have (as my husband affectionately calls them...) monkey arms, so I have been struggling to find one that fits properly, especially when coupled with my less than athletic shape... This jacket is awesome. It's warm, light, non-rustly(!), and very nicely styled. It fits fantastically. Very very pleased.
This jacket is my absolute new favourite! Great fit (true to my 14), with bottom warming properties due to the longer back length. Arm length is excellent, long without being silly - can raise arms without getting chilly wrists. Warm and cosy as expected. Colours are fab!
Love the colour and weight of this jacket but it’s quite a neat fit especially across the chest.
