Thule Subterra Duffel
An 18L backpack is great, but it’s not gonna take you around the world. Thule’s soft-sided 40L Subterra Duffel (on sale for $169 at Backcountry) organizes your gear and keeps it neat. The contents of the main pocket zip under a mesh flap. Shoes store in a separate pocket that doubles as stowage for dirty clothes, and a third zip pocket holds wallet, keys, passport and anything else you’re tempted to jam in. A removable sleeve with a power pocket holds a laptop and tablet. Grab handles on all sides make it easy to hoist overhead or snag from a vehicle. And backpack straps make it comfortable to carry hands-free. A pass through sleeve slides over the handle of a standard rolling bag when you’re bringing more than one bag, and rounded corners help it slide into any overhead.
