Mammut Ultimate Light Hoody (2014)

Far and away the lightest soft shell we looked at in this test, the Mammut Ultimate Light Hoody, by its rather cocky name, has a lot to live up to. On paper it adds up: Gore Windstopper fabric provides premium protection from gales, while remaining relatively breathable. That said, you’ll still heat up if working hard, and for this there are pit zips under the arms to avoid condensation. You get a gadget-sized pocket in the chest (with an inner earphone hole for music on the move if that’s your thing), two hand-level pockets, a hood and a good zip with a generous windproof stormflap behind it. The material is very soft, and there are decent hooks for hanging and drying, which are always welcome (but not always present) on outdoor jackets. It does have a few quirks that may or may not put you off, though. The sleeves don’t have a whole lot of room in them; it’s hard to imagine them fitting over a thick base layer on even fairly muscled arms with space to spare, and not everyone will like this ‘closer’ feel. Wear the Mammut Ultimate Light Hoody with a T-shirt-style base layer, and then the feeling of the cold pit zips on your arms isn’t the nicest. The pockets sit quite low, extending below hipbelt level. And while the cuffs are the non-adjustable type and are okay, the elastic is quite thin and so not the most comfy. There are also thumb loops, which are take-it-or-leave-it additions. The hood is non-adjustable and unwired, so either fits or doesn’t, and it would be nice if the branding was a bit bolder. Presumably if you’re spending £170 on a Mammut jacket you’d like to shout about it.

Lightweight and boasting great quality, but the Mammut Ultimate Light Hoody’s fit and versatility suffer for being stripped to the basics.
