Mammut Shells?

Does anyone have any experience with them? Are they good? Do they breathe? How's the fit, durability, waterproofing, etc?

I have the Norward Pro pants. The material is more breathable but not quite as durable as Gortex Pro. The fit was great in the legs but the fly was oddly placed, which made them hard to pee in through all my layers and my harness. Short story short, I finally decided to get rid of them when I couldn’t get “myself” out to pee at a rap station during a storm at 5000m   . Now I’m back to all Arcteryx again.

Good to know. I think it's between the two brands at the moment for top layers, budget constraints force me to stick with the OR Helium pant for the time being.

Any experience with the jackets?

What iteration of the pant do you have? Mammut's website states "we have used a robust, lightweight and elastic GORE-TEX® Pro material..."

I have the very latest ones, just got them in December- it does look like they are Gortex Pro indeed. Not too sure why the durability didn't seem to hold up compared to the Arcteryx stuff I use, it could have just been unlucky. I got quite a 4-5 small holes in them after about 14 days of use.  Again, could have just been unlucky.  Even with that removed though, they are still not my first choice of pants.
