So I spent over 60 days hiking above treeline (10k to 14k feet) this summer, easily 700miles total. In May I bought a pair of Keenes, their nice US-made ones and they literally fell apart by mid August. I spend a lot of time carrying a pack.
I have two packs: an Osprey Kestrel 38L and TAG Mountain Ruck. The Osprey wins hands down. It’s holding together beautifully. No hesitation shooting off it suppressed, muzzle blast might eventually damage it though if you don’t use a can. It can fit a folded 16” RPR, and you could camp out of it for a week if you had ultralight gear and your dog carrying saddlebags.
It may be too small for you, but I’d check out their other packs if that’s the case. Plus, you just look like another hiker on the trail.
