World-class insulator for anywhere cold.

The Mammut Men's Eigerjoch Down Jacket warms you on frigid ski tours, freezing belays at ice crags, and anywhere cold from the city to the alpine. Light and lofty 800-fill down insulation makes the Eigerjoch surprisingly warm, superlight, and extremely compressible and packable. A double-chamber construction overlaps baffles to eliminate cold spots, and Mammut added synthetic insulation at the back and underarms to stay warm when sweaty and wet.

Mammut wrapped the Eigerjoch's light, protective, and innovative insulation in Pertex Endurance for extreme water-resistance, excellent breathability, and ultra-thin air permeability. Endurance's air permeability breathes the moment you put it on, as opposed to standard breathable fabrics that only start breathing after you start sweating. This down jacket also features Lycra hand gaiters with thumbholes, an adjustable drawcord at the hem, multiple pockets, and an additional packing bag for compact storage in ski packs.

Great Lightweight and Super Warm Jacket!

  • Familiarity:I've used it several times
  • Fit:True to size
  • Height: 5'8"
    Weight: 150 lbs
    Size Purchased: Medium

This jacket is super lightweight for the size and super warm. I'm 5'8" tall/150 lbs/38R chest and the size Medium fits me excellent. I got the Black color which looks great with it's neon blue lining. The jacket, when not cinched, is longer (down to mid thigh) than I'd expect which is great for providing coverage but it can also easily be cinched up and worn with the hem at the waist. There are lots of great things about this jacket but things that surprised me was the quality of the materials and fabrics. The tailoring is also precise (there is no extra bulk of fabric anywhere) and all the minor details are well done. I think Mammut changed the design slightly for the 2015/2016 season. The zipper pulls and cinch toggles are different on my coat versus the last year coat that I seen in the stores. Also this year's Eigerjoch seem to wear lighter and warmer than before.
This Eigerjoch is perfect but the only thing I would change are the ultra weak velcro closure tabs on the storm flaps. Unless you zip the central zip up those velcro tabs won't stay close-especially the velcro at the hem which just stays open and never really catches. I would have also wanted an extra zippered pocket on the inside chest for my mobile device even though the two mesh bucket pockets are enough. I also removed the bright orange zipper pulls on the pockets. They were just too much for me.
