I bought my boyfriend the drift waterproof backpack for his birthday and he is over the moon. It’s so comfy and so much space without feeling to big. The big pockets on the front and sides have made it perfect for our recent holiday when we’ve required a lot of water and have been hiking! Just to note there is no waist strap which he is fine with but I found it weird at first as I cycle and I am use to having on mine. After using it though the bag is so balanced, you really don’t feel like you need it.
