I disagree. I own a fanatic suit it is great. It is well designed and super warm. For where I hunt it is just about perfect. I don't pick up any more burrs on my way in than any other hunting clothes I wear in. Actually because its mid to late season gear all the leaves are off and those annoying stick tights are all gone anyway. There are plenty of opportunities to pick up burrs on my walks, but like I said I don't notice any more than other clothes. My only complaint with the long berber is that it can feel bulky in spots like the inside thighs, and bibs under the jacket. They did a nice job with the zone insulation, but IMO they could have use both berber and the stratus material...put the stratus material at the top of the bibs where its under the jacket, the inside of the thighs, and the whole leg from knee down if you are worried about burrs.
I walk in probably an average of a half mile to stand and then climb up in a stand and sit for anywhere from 4 hours to all day on occasion. It works great for this. It is super warm and most days you could wear it and a t-shirt and be warm enough down to the 30s. Below that combine with a thin merino base layer and the fanatic hoodie and I can sit no problem in sub freezing temps.
The camo is designed for elevated wearer meaning in the tree stand, and I never got busted in a tree once. My hunting partners who have seen me up in a tree says it disappears. The pocket design is super well thought out. It is quality gear.
My Sitka duck hunting gear is very nice also. I have been all over mountaineering, hiking, climbing, etc. and have owned a lot of gear. It is as good as any of the top branded mountaineering gear from arcteryx, patagonia, etc.
