This rucksack is amazing, it's so light and the weight is distributed exactly where it needs to be. Having the hip pads molded to fit me means the bag is even more comfortable to wear, and the best thing is if my hips change I can get the pads remolded up to 8 times. Also, the top detaches to become a bumbag, perfect for carrying personal items when you don't need a daypack. The bottom of the bag is ultra tough and the water-resistant finish keeps all your items perfectly dry, and to top it all off the product has a life-time guarantee, how awesome is that?
