    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.

    I miss you...

    • Size Bought: Large

    I had this jacket for about 1 year before it was stolen from my car. I still miss it to this day, which is why I am here, looking at many emotions. I wish I still had you, Eigerjoch, my sweet. This jacket is so warm and so comforting. I would recommend it to anyone. Definitely don't leave it in your car though.

    The Envy Of All My Friends

    This thing in warm. The warmth to weight ratio is amazing and I love the two big mesh pockets in the inside for keeping things warm during winter camping missions. Have used it for winter ski camp trips, cragging, and cold days around town. The light weight face fabric has held up well to my abuse as well.

    Great puffy replacement

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

    This jacket is a lot less bulky than traditional down puffy jackets but the double baffle design retains all of the warmth. I agrees that the fabric isn't super tough but I'd wear a shell over this if I was to use it where it could snag on something. The fit is fantastic and every detail is well thought out. My only criticism is that the zipper could be beefier (and the left side zip takes some getting used to).

    Serious loft and value

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: True to size
    • Size Bought: XL

    Can't wait for the real cold weather but woke up this morning to the low 30's and used the Eigerjoch on my morning hike up to about 10K feet were it was in the teens. This puffy is amazing, huge loft and it is so light for how warm it is. Fabric and the make is really high quality as expected from Mammut. Love the look of it and especially the hand gaiter/cuffs. you have the option to use them or use like regular cuff with no compromise. Also love the grippy stretchy stuff at the bottom. This really seals up well and will keep you warm. For the money it seems like the best heavy down parka out there. Love the dark blue color!

    Great Jacket

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

    I have had this jacket for 2 years now. I can certify that it is SUPER WARM even for the winter in Montreal. I can probably go to -10 or -15 Celsius with just a t-shirt underneath and I am someone who always feels colder than others.

    With a T-shirt and my Patagonia fleece, this Jacket can easily handle cold of up to -30 Celsius. Wind doesn't go through this jacket easily.

    This Jacket also has the best hood in terms of fit, it is also easily adjustable, once you wear the jacket with the hood, it's like being in an impenetrable fortress.

    The Lycra Hand Gaiters are great and also look cool.

    My MAJOR COMPLAINT about this jacket is that the fabric isn't very strong. Mammut Should have used 30 Denier Fabric. I have a large tear on the inside waist pocket that I had to cover up with duct tape and also there are a few small holes on the arms. If the fabric was tougher, these issues would not have arose.

    Also it's hard to carry a backpack with this jacket because of how slippery the fabric is in this jacket. Seriously Mammut change the face fabric.

    If this Jacket was made with Gore Windstopper or Gore-Tex it would easily be the best jacket on the market. It would also probably look better in these fabrics.

    Not The Best Base Camp Coat!

    DEC 2016 EDIT: I got rid of this jacket after the winter 2015/2016 season because I had several issues with the warmth retention (cold spot down the center zip), durability (outer fabric was too thin) and lack of exterior pockets.

    -the center zipper is reinforced with the thinnest of storm flap that anchors down with three wispy velcro tabs. the velcro tabs did not stay connected and when walking into wind the poorly insulated central zipper left a cold spot down the length of the zipper as well as across the chest. I ended up wearing too many layers to keep warm in anything below 10 degrees F.

    The outer fabric is sensitive to snags and abrasions that you get from any sort of contact with the outdoors. The seat region was starting to wear from several sit downs on logs and stone surfaces during at camp. Light to moderate wear in urban environments are fine but if you put it thru the wringer then yeah it will suffer.

    Lack of pockets also made me give the Eigerjoch up for the more handier Montane Deep Cold Down Jacket. When you wear this at base camp and not carrying around your backpack I find large map pockets and separate hand warmer pockets useful especially since the Eigerjoch does not have mitts holder D rings stitched in. Pockets to hold large winter mitts would have been an alternative. Also when you zip down the hand pockets you tend to get cold spots inside the coat. It is a good enough coat for many but at the $500 price tag and what I need in an outdoor winter base camp coat I had to get rid of it. I would give it 1 star but I do think this will be a great coat for young urbanites and suburban back yards! See my original review below and I also have a video review on Youtube.

    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.

     Not The Best Base Camp Coat!

    I typically wear a large but it sounds as though this brand might run a little small. 5'11" 195 and worried it could be tight. Any suggestions?
