    Meron IN Hooded Down Jacket

    The Men's Mammut Meron IN Hooded Down Jacket adds an abundance of warmth at less than a pound to your alpine arsenal. It boasts the highest fill rating for an incredible loft that warms you up without weighing you down. 900-fill down is so lofty that the jacket compresses into its own pocket for compact packing. Complementing the ultralight insulation, the jacket's Toray ripstop shell is also lightweight and ruggedly resistant against light moisture ranging like snowflakes and spray. The lining is so light that it's semi-transparent, so you can see the down inside.
    • Ultralight down jacket is surprisingly warm at high altitudes
    • 900-fill down insulation is the loftiest and most compressible
    • Toray ripstop shell is water-resistant to shed light moisture
    • Hood adjust over beanies and helmets
    • Backpack-and-harness-compatible side pockets
    • Jacket stows inside side pocket

    Extremely Warm, Lightweight

    This jacket is the lightest down piece I have ever worn. It feels like you don't even have a jacket on at all, yet still is extremely warm. I've used it as mid-layer on bitter cold days at the mountain and it is amazing. It also packs very small. I love the depth of the pockets and seamless zipper design on the side pockets, which is very stylish. For how much down is packed in this thing, you would be surprised on how light it is. If your looking for a very lightweight down jacket, I would highly recommend this one. It's definitely a must have for me for warmth, and weight.

    I finally got rid of my old puffy and got this jacket in october. it's really light, and I definitely would not want to beat it up, but for a belay parka or puffy to throw in my pack for ski touring this is by far the best jacket I've ever worn. it's super warm, I've used it to belay well be low zero F, but it still packs down to about the size of a small cantaloupe melon. I always get my puffies large to fit over another jacket, this runs a little small though, I bought a size bigger than normal and its perfect.

    I have worn this jacket to the summit of Mt. Rainer and Mount Kilimanjaro. It is incredibly light and when "every ounce counts" this jacket will give you warmth without adding the weight that most other jackets give, thus giving you an advantage over other climbers. However, because the material is so thin, it is prone to rips. I have patched to very small rips with Gorilla Glue. DO NOT wear this jacket when walking through blackberry bushes or a rose bushes or hug a cactus while wearing it...but why would you be doing that in a high-altitude parka anyways? And since you should be wearing this over all your clothes, get a larger size than you expect. I got XL, and I'm a normal sized guy who wears Medium tshirts. I needed XL to fit over all my other jackets. Summary: I love it, and when I use it for what it is intended for (super cold summit days) it is PERFECT.

    Great gear for cold days

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

    Always wanted an arrow in my quiver for those really cold winter days. Last weekend was one of those days 15F in Colorado mountains. So tried Meron Down for my backcountry ski trip. It takes a bit of faith that this would work - it is very light and almost feels like its not there. Wore it with just a baselayer but it kept me warm - too warm in the trees - so had to unzip. above the treeline - it felt comfortable zipped up , and on the ridgelines and the top of the peak - it dropped the hood and zipped up all the way - it did the trick. I don't think this is "one jacket to rule them all" - since i didnt feel comfortable skiing down with it - felt it wouldnt hold up if i hit a branch - so put a hardshell over it all said and done - i am pleased for it - very light , very warm and reasonably stylish

    First off full disclosure, I'm a sales rep for Mammut. I recently got a Meron IN for myself. Nearly ten years with the brand this is one of my favorite Mammut pieces ever. So warm and in fact too warm for my everyday Colorado front range jacket. But wearing a t-shirt underneath is all you need for temps around freezing. Layering up for cold outdoor pursuits is great and the weight is impressive, the no bulk feeling is awesome. Fit is spot on and runs true to size with the typical longer sleeve length so no gap between a glove. fabric is super cool and the photo does not do it justice. Get one and you won't be disappointed

    I'm mainly writing this review because there are none for this jacket anywhere as of yet and this jacket deserves one. First off, this jacket is insanely light. It has something like 110g of 900 fill, which I was concerned wouldn't be warm enough so I didn't take the tags off until I walked around in 25 degrees with a t-shirt underneath. Trust me, it's warm enough. Secondly, the fit is awesome. I am 6' and 155 lbs and it basically feels like it was tailored for me (medium size). It looks and feels fantastic. I could see a larger person around the middle not being as psyched on it, so keep that in mind. I'll write a follow up after more use.

    Follow up thoughts?


    I think I saw somewhere that the outer fabric for this garment is 7 Denier. Is this correct? If so, is durability going to be an issue? Also, is it DWR treated?

    Yes it's 7 Denier. Durability is almost always compromised when you go ultra-lightweight, and this jacket is no different since it is as ultra-lightweight as possible. I would not suggest this jacket if you need high durability. It is water repellent and has a DWR finish.
