Eigerjoch Hybrid Insulated Jacket

Part of the Eiger Extreme collection from Mammut, this jacket blends some of the best materials on the market for superb results. Pertex® Quantum Air comprises the majority of the outer of this jacket- a surprisingly tough lightweight wind- and water-repellelent material that also breathes well. Backing this is the lining-free Polartec® Alpha® Direct, which is ideal for retaining heat without build-up. Together these materials protect and insulate, but the fit comes from the intelligent addition of Pontetorto® Tecnostretch®, a breathable fleece that allows, along with the Georganic 3D Technology and High Reach Construction from Mammut, the freedom of movement we've come to expect from the Eiger Extreme range, whilst the jacket remains sat comfortably on the body.

Built into the jacket, there are 2 climbing harness-compatible cross-over front pockets, flat thumb loops built into elastic cuffs, and a hem with elasticated segments for a better fit. The jacket also has MAMMUT CONNECT built in, a technology which, among other things, allows you to register your product and extend the warranty.
