For those of you flying on a budget with carry-on only, the Cotopaxi Allpa 35 liter travel pack first even Norwegian Air’s rigid standards for international flights. The top side is TPU coated 1000D polyester, to shed dirt and wet, the underside 840D ballistic nylon to shave some weight, and don’t worry about getting caught in a storm: this comes complete with a rain cover. Suitcase style zip opening for clamshell packing is supported with a side shortcut zipper so you can access the main compartment in tight quarters. A padded laptop sleeve and tablet storage give safe space for the tech, and a top zippered pocket provides access to essentials, like the wallet, passport, earphones, and charging cords. With stowaway pack straps and a detachable hip belt, this is a great piece for those who prefer to travel light (and cheap) without paying extra for the inconvenience of luggage lines.
