This is the backpack I got from amazon - only £16.99! Basic but has loads of pockets and is enough - I travel light. Also have a smaller daybag version. But that's it - all my belongings in there for 2 months

Always support your local Charity shops - I picked this up for about £2, yes its a couple of years out of date - but still full of a load of valid and interesting info! Thanks to the Red Cross in Chorlton, Manchester :)
