Eiger Nordwand Advanced Down IN is a belay jacket for severe cold, filled with 320 grams of 900-cuin RDS-certified hydrophobic goose down. Mammut Wall baffles hide the stitching to reduce cold spots across the 875-gram build.
The recycled 20-denier Pertex® Quantum Pro ripstop uses Diamond Fuse filaments and a microporous coating for better abrasion and weather resistance. G-LOFT® synthetic insulation is placed in moisture-prone zones where down needs support.
A three-way helmet hood, down-lined collar and twin draft tubes seal exposed positions. Harness-accessible pockets, internal mesh storage and a two-way zip make the relaxed cut easy to layer over a climbing shell.
