By combining the best qualities of a duffel and a messenger bag with full waterproofing via a rolltop closure, the 32-liter Outdoor Research Rangefinder Seabag won over all testers. The supertough but lightweight bag both sheds the wet and floats, meaning rainy commutes and canoe trips are no problem. A big exterior pocket stores your tablet, phone, and pocket gear.
