after looking into it i have found it is essentially just a box with straps and waterproof material maybe ill just get another backpack.
what is making me lean towards a messenger type bag the most is the design with the whole flap opening very wide but still covering down to the bottom of the bag meaning if it can fit in between the clips and the top of the flap it can be carried (more or less) for example wheels and frames are a real bugger to carry with a backpack (without cable ties or bungie cords) but can quite easily be attached to a messenger bag
