A warm, water-repellent and lightweight insulated jacket - exclusively available at GO outdoors.
Built for alpine activity, Mammut's Xeron Jacket
is made using Pertex Endurance fabric with their Ajungilak OTI Climate fill insulation, which makes it lightweight, tough, breathable and water-repellent.
Designed with articulated elbows, it lets you move without restriction, without the fear of the sleeves riding up to expose you to the elements - making it great for climbing or scrambling in inclement weather.
The hood is under-helmet compatible with a stiffened peak and gives you a great level of adjustment, letting you find a secure and protective fit every time.
- 2 raised zip secure fleece-lined handwarmer pockets
- Zipped chest pocket
- Drawcord waist adjustment
- Hook & loop cuff adjusters
- 2 way front zip, ideal when wearing a pack or harness

Awful build quality, 02 January 2017
By steve n (UK)
3 days ago I bought this jacket.
After ONE walk with a lightweight backpack to the climbing wall the Pertex outer is ruined from just the straps against the outer, leading to tears and pulled threads.
Appalling performance for a jacket in this price range.
Have contacted Mammut directly to question about QC issues, bt will be returning this jacket as its not fit for use if a 10 stroll can destroy the outer.
Warm Yet Cool, 04 February 2016
By Jacob (Wigan)
purchased this jacket while on sale at 18%
i was fed up of being cold so decided i needed an insulated jacket, and this jacket doesn't disappoint the quality is outstanding the only let down is the slightly snaggy zip, the mix of vertex endurance on the outside of arms and hood plus vertex quantum give great weather resistance.
plus it looks the part
Awesome jacket, 12 January 2016
This jacket has been with me mountaineering in the Caucasus, the Alps (in summer and winter), ice climbing and rock climbing. It's perfect - fit is great, it's durable and I don't have to worry about keeping it bone dry. Not as warm as many big puffy down jackets but that's not what it's trying to be.
As a bonus, it's a decent price and it looks cool enough to wear day to day too.
Excellent, 12 October 2015
By adibranch (Derby)
Had this a while now, and used it in cold weather walks, as well as on some overnight camps on the hill in autumn cool and windy conditions as an outer layer.
It really is great.. Its a GO exclusive but its actually the same as a Mammut Rime Pro but without the interior mesh pockets. Its warm enough for standing around in on cold nights (although for winter you'd need something a little more substantial), its light, packs down well, and the hood is excellent with cinching all round. The material is soft, comfy, and warm, and the fleece lined handwarmer pockets are just another added bonus.
I love this jacket.. i'm hoping it will take me into winter as a standaround jacket for nights on the hill, but I think it will be pushing it for warmth, so probably not in all honesty. Don't let that put you off though as it really is incredibly warm and comfy.
Zip permanently snagged up, 05 February 2015
By Electronut (Sheffield)
In my first review I said that the zip was sometimes a pig. Well today the zip has completely snagged up and I can only take the jacket off over my head. Such a shame as I just love the performance other than this serious flaw. Taking it back tomorrow.
