Down Jackets and Synthetic Insulation

Whether you’re moving fast and light, working on a hard boulder or crawling out of your tent into an Alpine landscape, our comprehensive range of insulated jackets has exactly what you need.

Powerful protection

We’re proud of our insulated jackets and we think you will be too. Our iconic Fantom jacket is designed to keep you snug on the coldest of days on high terrain, while the lightweight men’s insulated jackets work as a powerful mid- or outer layer.

Our synthetic jackets provide reliable warmth and can be packed down for those just-in-case days on the hillside. For those in-between-weather days, an insulated gilet is perfect to throw on as a mid-layer to ensure you keep your core nice and warm.

Materials and sustainability

We always use down from non-force fed and non-live plucked sources and it’s Responsible Down certified. Our down is also hydrophobic which keeps you warm if you’re caught out by rain. Our synthetic insulated jackets are made with PrimaLoft® with a DWR coating for added water resistance.


RDS Certified Downtek Hydrophobic 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.

Downtek water repellent treatment is PFC-Free and makes our down less susceptible to moist/humid conditions, staying lofted for longer, keeping you warmer and prolonging the overall lifespan of your down.

Primaloft Silver Eco: 100% Recycled Warmth

Inside our Kanyo jacket you'll find nothing but 100% post-consumer content.

Primaloft Silver Eco comprises of bottle chips that are reprocessed and spun into fibres finer and softer than cashmere, delivering uncompromised loft and warmth.

RCS 100 Certified Recycled Down

Our Filoment Hoody and Vests have never felt so warm. Filled with Recycled Claim Standard certified down and verified by a third-party to ensure it is 100% recycled and traceable content.
