Wear a daypack for enough hours and you will know—maybe better than you want to—whether you love it, like it, or might chuck it off a cliff. I hauled Marmot’s Aquifer 24 hydration pack on a couple of ultra-hikes on opposite ends of the country, in very different terrain and climates: a 17-mile, 6,800-foot, 15-hour, June dayhike over four summits in the Northern Presidential Range in New Hampshire, and a 25-mile, roughly 4,000-foot, 12-hour, late-May dayhike off the South Rim of the Grand Canyon, to take a full measure of the Aquifer’s comfort and functionality.
