Hi Matt. I generally don’t weigh my pack before I head out on a trip, but a rough guess would be around 55lbs. for a 2 or 3 day backpacking trip. My camera gear including tripod weighs around 20lbs. I always bring along all my camera gear unless I’m absolutely positive I won’t need a specific lens, which usually doesn’t happen. My other backpacking gear is pretty lightweight and I try to pack only the most essential items. Food is usually the heaviest part of my overnight pack even though I take mostly freeze dried dinners, instant oatmeal, energy bars, and such. Hope this helps, have fun in Glacier!
