The best Prime Day backpack deals for travel include discounts on durable, anti-theft backpacks and weekender backpacks that double as a carry-on.

While sticking with the 1,000 or so travel stores that carry baggallini products, the founders are making inroads onto the racks of G.I. Joe's, Harrods in London and Marshall Fields.
