I went through some nasty briars and clear cut areas and didn't tear mine at all. I figure I got lucky because it is thin and I would not push it that hard again.
The Teton rain gear is tougher than it appears. I've used it on quite a few duck hunts. I bought it when they first introduced the Teton line. So it's seen a few years of very wet hunts.
If you think it might rain off and on and you want something small, light, and something that doesn't cost too much, Teton. If it's going to rain the entire hunt and you don't mind the little bit of weight and size bulk, I like the Chugach rain gear.
