In reply to tim carruthers: Had a JW rucksack for about 5 years back in the late 80's/early 90's that I lived out of, literally. Totally bombproof and really well designed. Really comfortable back-system that seemed loads better than other sacks at the time. Was stolen off me with all my worldly goods as I slept on a train to Bedford
Got a new JW rucksack afterwards and it is still going nearly 20 years later. Needs a couple of zips fixing, but still going strong. My (far newer) Podsac Expodition is the nearest I have in terms of toughness.
Well thought out and well-designed gear, well it was all those years ago. The old garage in Capel seems to stock a bit of JW gear.
