In reply to tedswag: I recently bought the osprey exos 58 and so far its been a great pack, its more than 3 litres bigger than the last bag I used, a 55 litre (can't remember the brand) and probably on a par with most market 65l bags. It is incredibly light for it's size, well designed and seems very strong. You could do much worse than one of these. The only problem is the price tag, £125 online was the cheapest I could find.
