I wanted a very technical softshell without insulating layer to cover a wider range of use (insulation being handled by the fleece) and a better heat control and with a great comfort while moving. I went for the Mammut Extreme Ultimate WS Jacket that I tested during my last mountaineering outings in April.


Ultra-modern and technical softshell jacket made of several protection layers for a perfect windproofness and a good protection in extreme conditions while still offering breathability and durability. It is best suited for winter and alpine activities.

Opinion :

This jacket is just perfect ; excellent protection, breathability and what a comfort! With this sofshell Mammut has designed a very nice cloth faithful to its technical, high-tech and reliable product line[...] All it’s qualities make this jacket one of the best softshell of my collection and I recommend it to everyone who is into mountaineering.
