Down Jackets and Synthetic Insulation
Enjoy endless winter chills with an Alpkit insulated jacket. Decades of design experience and expertise, high-quality materials, and innovative technologies have been combined to create our down jacket and synthetic insulation range. After all, no one likes being cold.
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
Our down jackets, Filoment, Fantom and Zone, are filled with recycled down from RE:DOWN, certified to the Global Recycled Standard (GRS). Any virgin down we use comes from non-force fed and non-live plucked sources and it’s Responsible Down certified. Their outer fabrics have a PFC-free DWR to shrug off light rain and snow. Our synthetic insulated jackets are made with PrimaLoft® with a DWR coating for added water resistance.
