Strip away all that’s not absolutely necessary in gear and the result often is something you use over and over again. From a 23.5-mile, rim-to-rim dayhike across the Grand Canyon and a 13-hour, mostly off-trail dayhike of around 20 miles in Idaho’s Sawtooth Mountains, to shorter dayhikes in Zion National Park, as well as a seven-mile trail run-hike outside Ketchum, Idaho, and rock climbing at Idaho’s City of Rocks (carrying just water on the run and climbs), I kept slipping BD’s Magnum 20 onto my back—just for its simplicity and, of course, because it weighs barely more than half as much as a liter of water.
