The reliable Eigerjoch Advanced In Hoodie jacket from Mammut combines down with synthetic fibers and benefits from the advantages of both insulation materials. The use of so-called hybrid constructions is increasing as many manufacturers recognize the benefits of the combined functions: Down provides tremendous heat retention, but has weak points in the insulation when the feathers get wet and clump. This is where the synthetic fiber filling comes into play, as it retains its thermal output even when wet and is therefore mainly used on the shoulders, hood, back and sleeve ends.
To ensure that every small rain shower does not cause a loss of functionality, the Eigerjoch Advanced jacket is covered with the high-quality Pertex® Quantum outer fabric and thus guarantees excellent abrasion resistance and reliable weather protection.
Side pockets optimized for climbing harnesses, a two-way zipper, an adjustable hem and a helmet-compatible hood are of course essential for sufficient functionality during alpine activities.
