I've worn wolfskin for 2 years. Doesn't weigh much, VERY comfortable, DEAD quiet, even when it's cold out. I brush against my tree quite a bit in stand, and it makes very little noise. It's durable. It will shed a light mist or snow easily, but not rain. You'll get wet eventually. It's got a very low nap and burs just don't stick to it, and what stubborn few do, brush right off with ease.

I wouldn't wear it when it's warm...say.....75* or more. It's got some insulating properties and it'll get hot in that climate. I layer under it and stay pretty comfortable.

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.
