the weight is fantastic for bikepacking.

when rolling the top and then buckling at the sides, my bag would open up if there was too much stuff in it. almost had a spill out at the airport.

BUT! even though they don't show it in any of the images, you can roll it up and clip the ends together, left to right, like you would any normal dry bag. you can then clip the side straps together and cinch the body to make it narrower.

the white version gets scuffed and banged up looking pretty quickly so hopefully you like that look (I think it's cool).
