I have two wolfskin suits.
Quiet
If it's Treated with DWR it pretty much water proof for hunting.
I will say it's not as tough as I heard. It did rip when in coat and pants this year.
All in all it's a good material IMO
I think it's main positives are comfort, soft and silent, and no burrs. The only real negative I can think of is wearing it early season. It's just too warm.
I would pretty much agree with mobo, only mine did tear.
