From Big Agnes’s outdoor-inspired travel line comes the redesigned Stagecoach, a virtual amphibian and, of the bags tested, hands-down the best hauler in the muck, slush, and rain. The 3,300-cube small is pictured, but it comes in medium and large as well. Thanks to its nylon-laminated membrane and welded seams, this carry-on really is waterproof, as one Colorado reviewer confirmed after a rain-soaked passage. As a traveler, the Stagecoach is easy, with a burly, retractable dual trolley handle and silky 70mm inline-skate wheels; deployable padded shoulder straps, so you can comfortably wear it as a backpack; and a sturdy haul handle for carrying as a duffel. Our only gripe: It won’t stand upright when loaded. 5.8 lbs;
