In case you nonetheless feel the coat has a problem, contact Filson. They're incredibly beneficial.-Dick
If either Patagonia or Arcteryx created moncler jacketss for hunting, I'd be using them and wouldn't be worried inside the least in their durability. But they don't, so it is un-oiled Tin Cloth for Upland with Filson Camo(not made anymore) and Orvis Gore Tex Camo parka and lengthy parka for waterfowl and ll Bean techy Blaze Orange set for deer hunting.
The only reason I'm not into the techy stuff is their lack of durability when put to rough field use. Likely OK when stand hunting or hiking cleared trails but when I made use of to hunt, I was commonly on the move and typically hike without benefit of cleared trails.
