I wear OR and Black Diamond gaiters. I wear them while hunting. All kinds of hunting. I like the OR Crocodiles and BD Frontpoints. The OR crocs are my favorite. The OR crocs might be a bit much for most folks. They’re designed more for mountaineering use. I think I have 4 pairs. I'm currently wearing a pair of black diamond front point gaiters. I’m on year 5 with this pair. I wear them for mostly hiking and hunting. They’ve seen use snow shoeing too.
I doubt you’ll find any terrain rougher than western chukar country. The bottoms strap holds up just fine. One trick of the trade is to cut a piece of webbing to size and thread the bottom strap through the webbing. This will add some protection.
I can pretty much guarantee that I’m rougher on gear and put more foot miles down per year than most here. I’m sure there’s some exceptions. I spend a lot of time outdoors and I put on a lot of miles on my feet, I can vouch for both the OR Crocs and the BD Frontpoints. Both are tough as granite and of very good quality.
