I have GWW wolfskin and my buddy has Sita. I like the Sita stuff, but my biggest complaint is it's SHINY. It made more like mountaineering gear for comfort and fit, not hiding from game. I think one reason why some camo is better than others isn't the pattern, it's the texture. The wolfskin is a low nap, very dull looking fabric, just like a deer (which is basically one color, yet hard to see). This is also why wool is an excellent fabric (even in plaid!)
Wolfskin in predator brown has worked for me so many times, in tree stands and on the ground for whitetail and mule deer. I just had a 150" WT buck look right at me from 25 yards away and he looked right through me, if you know what I mean. He saw something in the tree, but didn't recognize a pattern and never gave me another look. I don't think that would have happened with Sita gear, even in the new digital camo. It has a shiny texture unlike anything in the woods. I can’t believe they don’t do anything about it.
Wolfskin with DWR is great for light rain and mist, and it can be regenerated. About the only complaint is it can be hot on early elk hunts as it has some wind resistance, so if it's hot out you will be too. But any other time it’s perfect outwear. You can always layer underneath with mountaineering underwear, even Sita stuff but I never understood why anyone needed camo underwear.
Jeff was great to work with too on customizing to my size and options. You won't go wrong with GWW stuff.
