In reply to Phil1919:
Clint, they haven't done a karrimor but their packs are poor quality. I used to work in a shop that sold them and the while the workmanship is pretty standard the design of some of their packs is as poor as most modern rucksack manufactures. Too many seams, too much leight weight material. My friend bought a pack (I think called the arete) aimed at climbing and skiing, it fell to pieces wiht very light use (days not months) and more concerningly both ice axe loops broke off. Luckily this wasn't somewhere which could have been dangerous, this thing was worryingly marketed at alpine climbers.
I have a very old 40ltr berghaus rucksack which I use as a crag sack and a winter climbing sack. It is completely bomb proof, well designed, good quality materials and stitching. The trouble today with a lot of rucksack manufacturers (not just beghaus) is there is a tried and tested design for a bag, it's made of one main piece of thick fabric with a thick bottom double stitched on and one seam down the back panel. This design works perfectly, never breaks, is relatively cheap to manufacture and therefore no use for a company looking to make money. Take a modern berghaus (or osprey for that matter) sack and there's about 20 bits of fabric about as thin as your grans tights, laser cut, hundreds of man hours on the design, the most expensive light weight material etc. etc. The end result is a very expensive bag which falls to pieces very quickly and saves you about 200 grammes.
You have 3 options, buy a cheap shit bag and replace it when it falls to pieces (ironically I got a 25 ltr mountain warehouse bag which is better designed and has lasted longer than my friends berghuas - purely because instead of spending thousands of pounds on a design they've just copied the design everyone else has used successfully for decades)
Secondly splash a load of cash on an aguille, blue ice or similar style pack. (there's lots of sack info on these forums)
Third get an older pack from ebay, karrimor, berghaus, pod etc.
