Thanks guys, I did look at Backcountry for cheap backpacking packs, but I already have the ILBE. I was looking for some firsthand experience, and if any glaring problems popped up.
Like I said, I want to leave more cash to put towards a good set of binos, and potential last minute things.
Kuiu is having a good labor day sale, and I thought about picking up an Icon Pro setup, but if the ILBE works, I'd prefer not to.
Idk if this is a rookie mindset, but I doubt 1 or 2lbs will be that big of an issue, being that I'm a big dude. (6'4 235)
The old civilian version of the packs- Arcteryx BORA- is a far better loadhauler, IME. Better frame design with actual load lifters. A guy your height won't be able to get the pack 'properly adjusted'. I'm 7" shorter and could barely get any lift. But the ILBE are spacious and tough, should easily handle antelope hunting.
If it's what you have and in the budget, just go hunting. The gear doesn't matter near as much as places like this make it seem. Enjoy your hunt and best of luck.
