I absolutely love this rucksack, loads of capacity but not a large rucksack, lots of pockets too, the layout of the pockets is great, the back part is very comfortable on the back.  The one thing I’d say is the side pouches for water bottles could be better, I’d have like stretch material and the cinch cords that thread through for the main compartment compression get in the way a bit when putting a bottle in and out of the pockets, this could have been better designed I reckon but it’s fine.  I love the hip belt pockets and that there is also 2 on the straps (1 with extra zip compartment) these strap pockets would be better with little elastic cinch straps but that’s ok.  I like the colour but wish there was a few more colours.  This is without a doubt the best rucksack I have ever owned (and I’ve owned loads) it’s just so so comfortable and so many pockets and extra expansion too, I truly love it and highly recommend it.  I’m 6’1” and the small fits perfectly on the tallest adjustable setting inside- which is such a brilliant idea and design.  Top marks to the designer(s) of this rucksack, very very very good job, so well thought out, LOVE IT.
