Just bought this and returning it.

  • Familiarity:I returned this product before using it
  • Fit:Runs small

I just received this jacket and there are definetly a few problems with it. It seems like Mammut (which I only use and am the biggest fan of everything they make) sacrificed wearability to cut down on weight! Im 5 10, 160 lbs, 38 US (48eu) and 32 inch waist. Every mammut product I have ever had I have been a medium top (every other brand I'm a small), 32 inch waist pant. This jacket fits perfect up top, but to cut on weight, the waist area is snug and the snow skirt is for a 28-30 waist, its ridiculous. Also, in the description it says it has 2 hand pockets. Again, to cut down on weight, there are NO pockets. Just the one front chest pocket. And the last problem is the hood. Everyones complaint is correct, it doesn't cover a helmet or zip up. And the zipper isn't horrible but not great.

So what I come away with this jacket is sometimes sacrificing an ounce or 2 of weight isn't really worth it.

Poor Zipper

  • Familiarity:I've used it several times
  • Fit:True to size

LIght jacket. Good fit. Good windproof material. BAD zipper! Front zipper stuck while I was in the mountains of Arizona during the winter. If it was not for the under and the mid layer I would have frozen.


  • Familiarity:I've used it several times

I bought this jacket because of its 3 ply gore construction and it's helmet compatible hood (alleged).

I took it to Japan for 2 weeks brand new to ski some side country powder in Niseko where the temp sits around -10 deg.C, or 14 deg. F.

The waterproof capabilityof the jacket was second to none an the powder skirt worked great (although my osprey pack made it ride up a lot but I guess most packs will do that to any jacket.)

The zippers performed well and the Large size fit me well at 5'11 and 85kg, there was enough room to layer comfortably.

This shell is super lightweight and great for touring and piste skiing but when the weather got gnarly I tried to pull the hood up and the thing would not fit over my helmet. I have an average size melon and helmet.

Bit of a bummer considering the verbiage from mammut states that the hood is helmet compatable.

The major regret for me is the durability of the gore tex active shell.

I had a chance to ski all kinds of terrain over there but found the best snow in the trees so that's where I spent the majority of the time.

On the last run of the last day of the 14 day trip I brushed a low lying branch with with my left arm and ripped the jacket in 3 different places, side by side.

Devistated to say the least.

If I could do it all again, I would go the stretch and buy the gore tex pro shell.

The active shell is just not durable enough for tree skiing in my book, it wasn't like I nailed the tree.

If you are hiking and skiing open bowls and Piste, this jacket will suit you.

But if it's durability you are after, go for the pro shell.

If I hadn't ripped it on the last day, it would be going back for a shell that is truly helmet compatible and made out of pro shell.
