I purchased this for going to Oz in 2008 and it's the bet backpack I've ever owned it hold a lot more that you'd expect and the detachable rucksack is great I use the rucksack everyday. I've used this on 3 backpacking trips and it still looks new! Is very well build and handle the stresses and strains of airport baggage handlers very well. Would reccommend anyone to get this or indeed any other Karrimor product
