We have three Jansport frameless packs (Alaska and the next size down - Rockies???). As Hikerdon wrote, they are not among the best, but they are not junk either. They are not even close in a number of areas to 3 Kelty frameless packs we have (and I rate Kelty as "Good" but not top-of-the-line). However, the Jansports are holding up remarkably well for our three sons and they certainly like them... FWIW, I never could get a Jansport frameless pack to fit me well - someting was just not quite right each time I've tried. But at the price we paid for them they were a great value - and when the boys wear these out they will have a good idea of what they like and do not like. No regrets at all about purchasing them despite my slightly negative reaction to them. And I like (for the price) the Jansport accessory pouches enough to use one regularly on a couple of other packs (I move the pouch from pack to pack - it's the contents that I want with me), as does my wife.<br><br>My brother has a frame-type Jansport pack (or two) and he likes it rather well. I have a more traditional frame (original model Freighter frame by Camp Trails) on its second or third set of harness so I'm pre-disposed to not like the Jansport frame... my impression is some folks love the frame and some detest it.<br><br>HTH,<br><br>Tom
