Osprey Ceres 50 ($179):
There are plenty of reasons for contingency planning, especially in high places, so the smart money is on those who carry the needed (and correct) gear. With the Ceres 50 (three sizes: 2,800, 3,000, or 3,200 cubic inches), you've got a climbing-inspired pack with enough capacity to swallow the essentials, plus the on-the-money features for tools of the trade. A removable framesheet and full-length stay keep the package light and flexible enough for acrobatic maneuvers, and the framesheet can double as a small sleep pad for bivy time. Its removable floating top pocket lets you overstuff the pack if need be—you can even use it as a detachable fanny pack. And with dual tool loops, crampon patch, shovel pocket, ski/snowboard straps, and extra accessory compatibility, you've got all the exterior add-on capabilities a well-outfitted climber needs for 24-hour adventures.
