First Look: Mammut Marangun

This cheery chap is the Mammut Marangun, which has been lurking in the gear cupboard, waiting for the temperature to drop. One look at the forecast at the weekend and it went straight into a rucksack.

It’s a lightweight insulated shell, made with Mammut’s own fabric Drytech Premium, which is waterproof to 20k mm and it’s filled with Ajungilak Comfort fibre for insulation. There are pit zips with mesh inners for ventilation and a couple of waist pockets with downward closing zips and a chest pocket, along with a wee inner pocket to keep your toffee crisp from freezing solid. The zips for the vents and the pockets are nicely styled to look like a single piece.  There’s a cosy little fleece patch at the back of your neck and the hood is also insulated and adjustable, but it’s fairly neat so I don’t think I’ll be getting a helmet on under there.

It’s primarily designed to be a cold weather trekking or ‘hanging about at camp’ jacket, and from my first trial it certainly fits the bill. The material is very windproof and it’s warm to wear. So warm that my down jacket only came out to play at the end of the day.  I haven’t got it wet yet, but to be honest I’ll be keeping this for when it’s snowing rather than raining. It strikes me as ideal for mooching about camp, or for wandering about in when it starts to get really cold. I’d even entertain it as a belay or ice climbing jacket.

The only downside I’ve found is the waist pocket height is a problem if you’re wearing a rucksack belt or a climbing harness, but it’s no big drama.  If my usually-reliable weather forecasting hen is anything to go by, this will be getting some action in the coming weeks. More shall surely follow.

    AC - How has the Mammut Marangun jacket treated you after some time with it? I’ve seen specs on it and read a couple things about it, but haven’t been able to try one out personally. Seems like such a jacket would fit my dry cold winters and windy\rainy springtimes with its touch of insulation, setting it apart from many hard and softshells. I like that it would allow for it to be a single layer for a lot of winter travels or just hanging about in coolish conditions, yet still not so burly it couldn’t go in the daypack on hikes ‘just in case.’ I’ve lately been looking for an outer piece with decent weatherproofing and some insulation, because rain around here in Montana means temp drops noticeably, plus the insulated hood will come in handy as windchill increases. I own an AtomLT midlayer with 60g primaloft…how would you rate the insulation in the Marangun (40g, 60g, etc.)? Thanks much, and keep up the good work…

    AC - Whoops, forgot to ask…any stretch to the fabric in this piece? I know on some DryTech pieces, Mammut claims a lot of stretch, but haven’t heard such in descriptions of this jacket. Speaking of the fabric, is it burly enough to take a bit of a beating by trees, rocks, etc., say backcountry skiing or bushwhacking a bit? That’s something I’m a bit wary of in my Atom LT, though it’s survived so far.

    MT - Hi AC, thank you for your kind words. The Marangun has been a staple this winter. It’s been my ‘throw on’ jacket. So not just mountain trips, but taking the kids out to the park in the snow and general family stuff too. Its pretty much like a fleece and shell combo but without the bulk. There is some stretch in there, although not a massive amount. Wind and weather resistance is good and its warm. I do overheat in it on uphills with a pack, even with the pit zips open, but when you pull it out of your pack on a windy cold summit its like a hug from your mum. The hood deserves special mention, it’s excellent. Its well shaped and nicely insulated, it’s like a shield of steel against the snow. I love it.

    MT - Forgot to say, it’s very sturdy. I’ve bashed mine a lot, off rocks and icy grooves when climbing in it and it still looks good. I’d say it looks like it will wear well.

    AC - Thanks much for the details about the Marangun jacket – sounded like it might be a winner for me, and I was able to finally track one down and try it on. Very well made and pretty darn warm from what I could tell. One weird question: does yours have lycra hand gaiters?? On every description I could find about the jacket online, including the Mammut website for that matter, it mentioned the Marangun having internal wrist/hand gaiters, but the Marangun I tried on didn’t have that feature, just velcro adjustable cuffs. Not a huge thing I guess, just a little feature I was expecting to find.

    MT - Dunno where the hand gaiter thing is coming from, mine has velcro adjustable cuffs. Weird.

    Jeff - Thank you for the detailed review of this jacket, I just have one question here, it has actually been asked by AC but I dont think I could find the clear answer in your comment.
    How would you rate the insulation in the Marangun (40g, 60g, etc.)?

    Thank you very much!

    MT - Jeff, as usual with these things, it’s subjective, some people run hot and some run cold. I don’t have firm specs for exactly how much insulation is in there. It’s not super warm, but plenty warm enough when you’re moving and for short stops in the cold on it’s own over a base layer. Even in the coldest conditions it’s fine when layered on top of a base layer and powerstretch midlayer. I’ve found that to be good for high level walking and ice climbing. I’ll put a big belay jacket over the top for prolonged stops in winter. I’m not sure if that helps you at all!
