Down Jackets

Down gives the most warmth for its weight and packs the smallest. Filoment is our light, slim micro-baffle range: the Hoody (650 fill power, 419g) and the Vest (246g). Fantom is our warmest, with 700 fill power down in big baffles and a helmet-compatible hood for winter mountains.

Down Jackets

Filoment, Fantom and Zone are filled with recycled RE:DOWN, certified to the Global Recycled Standard (GRS). It comes from old jackets, duvets and sleeping bags, some of them sent back to us through Continuum, and it's tested to the same fill power standard as new down. Here's how it gets a second life. Any virgin down we use is RDS certified and audited by a third party, so it comes from birds that are not live-plucked, force-fed or mistreated.

Designed by us, direct to you

Our gear goes directly from us to you. We design our insulated jackets here in the UK, and our warehouse team sends them straight to your door, or you can buy them in one of our stores. There are no distributors or retailers in the chain. It's how we keep making high-performing jackets at the best possible value.

What fill power means

Fill power measures how much a gram of down lofts. Higher fill power gives more warmth for the same weight. How much down a jacket holds matters too: Fantom has 290g of down in a men's medium, Filoment Hoody 156g.

Water resistance comes from the outer

A PFAS-free DWR on the outer fabric sheds light rain and snow and helps keep the down dry and lofted. In sustained rain, wear a waterproof over the top.

Wash, repair, recycle

Washing a down jacket restores its loft. Use a down-specific wash such as our Down Jacket Wash, or send it to our repair and down wash service.

When it's finally worn out, send it back through Continuum and the down can become RE:DOWN.
