One type that you'll either love or hate are the canvas day packs from Duluth Pack (not Duluth trading co) & Frost River. I shredded every other pack I ever owned but still have my Frost River "nessmuk" pack going on 15yrs. Yes, they are heavy, hang lower on my back than I like, I got optional chest strap and pads I found it as decent as some of the others I had.
Keep in mind that I'm not a weekender, I wear a pack daily for work, wear it on my "off days" training hounds and guiding hunters, going through thick brush where all the straps on some of the others catch on everything & get torn off. They are old school, but tough as nails. The pouches work great for my trauma kit, 48oz bottle, fire kit, and the main compartment holds whatever, mine is 15-20lbs depending on season. No camo, no tacticool look, just an old school pack. Their bigger packs I don't care for, but the day packs are the only ones I don't litter pieces of all over while in the brush. I think they look cool as they wear too.
