Chrome's Yalta Rolltop Backpack is a great do-it-all bag. Commuters love how comfy it is to ride with, travelers like the large volume and students love its simplicity. Everybody loves its tough, weatherproof 1000 denier tarpaulin outer shell and floating bucket liner with a rolltop closure for serious rain protection. They all agree on the full-length back zippered pocket section that includes a built-in 15-inch laptop sleeve. Front zippered pockets give you extra organization and all the buckles are metal for long-term durability. On foot or on the bike, carrying it is a pleasure with an ergonomic EVA foam back panel with Airmesh shoulder straps, a stabilizing chest strap, and super-visible 3M reflective panels.
