This rucksack is huge, absolutely huge. It seems to be really well made, should last quite awhile. Inside has enough room for everything I need to carry on a camping trip. There is space for my tent, mountain boots, sleeping bag, camping stove, change of clothes for four days, waterproof jacket and there is still enough space in the pockets for all the other bits if gubbins that one would need. With a bit more clever packing I'm sure I could get a lot more in.
This bag is fantastic for the money. Very well thought out. The adjustable height straps are a huge bonus too.
