Chrome's Romer Messenger Pack gives you big capacity with the 2-strap comfort of a pack. An outer shell made from 1,050-denier nylon keeps it tough and an independently suspended weatherproof liner keeps it comfortable. This design excels even with heavy loads and it eliminates any seams exposed to the outside elements. Further burliness comes with military-spec seam bindings and aluminum cam-lock buckles throughout. None of this means anything if it doesn't ride well, so you've got an ergonomic EVA foam back panel with mesh shoulder straps and a reflective compression strap to keep the load in place. Organization is easy with multiple pockets including a side water bottle pocket, an external slot for pens or tools and even a pump sleeve.
