I'm not in the US so hopefully someone that is will take the wheel, but meantime I'll say this:
I've been using one of
these as my load hauler for something like 15yrs. I like 'em. It's not light but if I've got to carry weight off the beaten track I'd rather it be with that than anything else.
I see a lot of folks recommending Osprey packs. I'm not surprised by that in the slightest. If price precludes those [or they just plain don't feel right when you try one] I'd suggest sniffing about for solid entry level stuff more on camping / hiking forums than here. It's not that there is anything wrong with here as such, it is more that at any one time the tide could flow in dramatically different directions. Get the right people here and you'll get look at Osprey 'cos.... Another thread might see an advocate of just stick 'pack 40L' in Amazon, and grab the cheapest one 'cos they are all much the same. And as I type there is a thread running on taking the ALICE pack as a serious contender, a position I can't skate with at all. If someone throws the first punch with Frost River packs are brilliant, and a couple of others that like the retro flavour chime in and coo, it can be amazingly hard to dislodge them. Whilst it may be obvious that those bags are really celebrity Gucci luggage that weighs a lot for little return there won't be much dissent, just apathy or withdrawal in disgust. We could apply that same momentum thing to other packs too. The cross section here is just too wide and you need to read targeted accounts from folks that demonstrably carry load repeatedly.
That said, I can tell you that in January this year a mate of mine bought a Vango Sherpa and it is proving to be pretty good. Not so long ago he was the guy depicted below, all Tilley hat and no clue. His gormlessness didn't matter so much in fine weather, it gave us something to laugh at. I told him flat out that he wouldn't be coming in other weather though 'cos he'd be a liability and a pest. I also told him that nobody was expecting him to shell out on high end stuff, just stuff that brought him a bit more up to speed with everyone else. Since then he's grabbed himself a Gore-Tex bivy and a tarp, Alpkit sleeping bag, a huge Exped SynMat 9, new stove and pots...blah. Finally, with his gear amassed he needed to find something fairly sensible to fit it all in. I suggested he look at the Vango Sherpa not because I think it is a fantastic pack as such, but more because it is a good pack at the price. True, they are a bit high street but they are also exactly the kinds of pack that are used for Scouting and the The Duke of Edinburgh's Award's stuff. The amount of them that must be in circulation is huge, and with that amount of them doing stuff from gentle sponsored walks to being dragged up Everest if there was something fundamentally crap about them we'd know. They are the entry level camping store stalwart for a reason. I certainly found it hard to find obvious fault in his. Anyway, that's exactly the same approach I'd suggest over there too. I don't know if you have those there. If you don't I'd be sniffing about for an equivalent among those same sorts of people.
