The roll-top design enables a wide-mouth opening, complete with chunky zip and magnetic holders and so you roll it over to cover the zip or leave it unrolled if you need to fill this bag to the brim. There’s a secret pocket on the outside and more pockets inside for all your tech things, and the medium and large sizes feature side bottle pockets.
