With 650 fill power ethically-sourced hydrophobic duck down to keep you warmer in damp conditions. The outer fabric is a heavyweight nylon with a DWR coating; the pockets and cuffs are lined with a soft tricot fabric; and Filo is longer than our other down jackets for full-on warmth against the cold.

Filo’s 2-way zip and removable helmet compatible hood are practical design features that make Filo our go-to winter down jacket.

For belaying your partner up Christmas Crack on the 25th December, torch-lit evenings on the gritstone, and all the days in between... Filo is guaranteed to keep you warm and snug winter after winter after winter.


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 to know.

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. You can wash it in a front loading washing machine with our detailed instructions (see the FAQs).

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.
