Eigerjoch Advanced IN Hooded Jacket

The Mammut Men's Eigerjoch Advanced IN Hooded Jacket would've been the envy of every old-timer to ascend the Eiger back in the day. This insulating jacket is packed with the power of 850-fill down for a level of warmth that any mountain climber dreams about, and Primaloft Gold Active covers the hood, back, and sleeve ends with insulation that stays warm when wet. Once the snow clears up, if you're feeling toasty, simply stuff it into its stuff sack that's disguised as a chest pocket.

  • Heavyweight insulator ideal for big mountain adventures
  • Pertex Quantum is durable, lightweight, and water-repellent
  • 650-fill down is high-loft for a toasty toasty torso
  • Primaloft Gold Active in hood and pits offers protective warmth
  • Vertical Motion and High Reach Technology for mobile performance
  • Drawstring hem and hood keep out jack frost's sneaky fingers
  • Packs down into own stuff sack chest pocket
  • Elastic cuffs and athletic fit provide low-profile functionality

Exactly what I wanted

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: XL

The color- bright, rich sheen, deep orange color. Fit- 44 jacket, 34 waist, 18 arms, fits like it was tailored for me. Lightness- floats to the ground like a kite. Warmth- 25F and breezy and I felt warm with a thin wool top. Accessories- hood fit's snugly on my hatted head, pockets to carry all my stuff (phone, gloves, keys, food bar), sleeves don't let cold air in, hem is also snug.

Good overall but missing a key feature

  • Familiarity: I've put it through the wringer
  • Fit: True to size
  • Size Bought: Medium

Fantastic fit and materials are the quality you'd expect from a jacket in this price range. However, it is missing a key feature - a chest pocket.

I can't work out why they didn't include one. Would make me consider another option when replacing.

Warm and Luxurious

    Incredibly lightweight coat for the amount of warmth it provides. Packs down reasonably well for long treks. Could easily last a lifetime.

    Great jacket esp when below freezing!

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: Runs small
    • Size Bought: medium

    Pleasantly surprised how lightweight, yet warm this jacket truly is. Nowhere near as bulky and

    Changing from Mountain Hard GhostWhisper

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: XL

    I bought this as a replace
    For my MH Ghost Whisperer. It is noticeably heavier, but drastically more durable. I only wear puffy jackets after hiking in to camp or sitting by a fire. A sweaty puffy is worthless. I bought it a little bigger to cover mid and base layers for cold Back Country nights. This product will and has severed me well thus far.

    I bought this down jacket, thinking it was a best in class product (most technical series from mammut). It turns out it is not at all breathable, and it feels like being in a platic bag. You need always to keep it open in order not to sweat, even in the cold. I have another down jacket, without this problem.
    I would not recommend at all, even if it looks really great from the outside...

    How to Measure:
    For best results, take measurements over your underwear.
    Measure under your arms, around the fullest part of your chest.
    Measure around your natural waistline, keeping the tape a bit loose.
    Measure around the fullest part of your body at the top of your legs.
    Using pants that fit well, measure the crotch seam to the bottom of the leg.
