I've got one ... I've packed out the backstraps and neck meat from a bull last year in it, along with daypack hunting gear. I didn't mind (it was my first elk ... so uphill at 1 a.m. and I was still so high I didn't mind anything) ...
I've used it for 2-3 nights out, and I've been comfortable with that. If you're looking for a mid-price-range lightweight camping pack that doubles as a daypack, it's not bad.
I'm going on a 1-night trip this weekend with it, and for that trip I wouldn't think about taking a larger pack.
Full disclosure: I don't know much at all about packs compared to others on this forum.
