Mammut Teton / Ridge (2015)


The latest version of Gore-Tex waterproof and breathable fabric is used in the Mammut Teton / Ridge, with its C-Knit backer, which is lighter, softer and less durable than Gore-Tex Pro. Two chest pockets and pit zips are also provided. The hood sports a large stiffened peak. A nice less obvious feature is the larger-than-normal Velcro contact areas on the cuff adjustment. Looks good so far. 5/5


The Teton for men comes in sizes S-XXL and the Ridge for women comes in sizes XS-XL. The fit is similar to others here, being unrestrictive with enough room underneath for insulating layers. There was only a small degree of movement in the cuffs and hem when I raised my arms, and the hood fits exceptionally well and moves very easily with the head too. 5/5


Gore-Tex C-Knit technology reduces the fabric’s weight by 10 per cent, improves its breathability by 15 per cent, and is softer and slides more easily over undergarments. So the Mammut Teton / Ridge feels more comfortable and less stiff than a Gore-Tex Pro jacket for example. You get pit zips to add further venting too. The pockets are not mesh-lined, so no leakage there. 5/5

In use

There are only two outside pockets, but you can fit maps in them and access them above a rucksack hipbelt. The hood peak is stiffened but not wired, so while it is okay I’d always prefer the inclusion of a wire so you can shape the peak if it gets deformed in a rucksack for example. Gore-Tex C-Knit is less durable than Gore Pro so a little more care is needed with this. 4/5


Gore-Tex C-Knit is a lower price per metre than Gore Pro and the Mammut Teton / Ridge has fewer features than some Gore Pro jackets, so its price is high. 3/5


The Mammut Teton / Ridge is a lighter, more breathable and softer jacket that is great for most hillwalkers, but its price is harder to justify than others’. 4.4/5
