Testers and test conditions:
I'm about 1.85m tall with a fairly long and strong upper body and short legs, and my weight fluctuates around 90kg. I therefore fall a little outside the classic alpine endurance sports figure. My activities with the jacket were wide-ranging, from ski touring and piste skiing to cycling and everyday life. In size XL, the jacket fits me very well. There is enough space for additional layers underneath, which is urgently needed for some activities. However, I have to admit that the jacket would be a little too short for me for pure freeriding on the board because it reaches only above my bum.
Technology and facts
The three-layer hard shell jacket impresses above all with its extremely high water resistance of up to 27000mm, which definitely puts it in the absolute top segment. I find it particularly astonishing that this water column is guaranteed with the light weight of only 420g. According to the manufacturer, the jacket is particularly suitable for use in alpine terrain and for ski tours. Accordingly, it is equipped with a number of practical features. I particularly like the helmet-compatible and individually adjustable hood as well as the large chest pockets, which can be opened with one hand using the cross grip.
The jacket is equipped with an incredible breathability of 48,000 g/m²/24h, which means that 48,000g of water vapour per square metre is transported to the outside in 24 hours. A jacket with a value of 15,000 g/m²/24h is already considered very breathable and the best jackets are in the region of 40,000 g/m²/24h, which makes this value of the Mammut Taiss even more impressive.
