Where can I get one of those big ortiled watertight bags in the backpack form I know they exist I used them all last summer. I live in the Lancs area. Thanks Dan

Do you mean ortlieb? If so, plenty of places on the web have them (tho' obviously if you meant ortlieb and were searching for ortiled that'll explain why they're so elusive!)

If you can't find one locally then drop me an email - I'd happily flog a spare 120L one I've got kicking around (perfect condition). Mines the canoeing one so no back system or waist belt, but two rucsac shoulder straps for portaging.

Thats just what I need how much do you want for it?

I've emailed you. If you don't get it, email me.
