A 15 mile day is a long one, but when you roll up on a pristine alpine lake without another soul in sight and set the Osprey Volt 60 Backpack down, all the hard work will be worth it. Best of all, you'll be able to enjoy your surroundings without stressing about back pain, because the Volt's highly adjustable back panel, shoulder straps, and hip belt will take the stress out of lugging heavy loads. The pack's LightWire frame and HDPE framesheet disperse weight across your body, spreading it between hips and shoulders, and the hip belt padding can be extended on the fly, so you don't rub your hip bones raw as you hike. With 60 liters of gear hauling capacity, the Volt has more than enough room for a weekend's worth of gear. Pockets at the lid, front, sides, and hips help you stay organized, and a removable sleeping bag divider provides a snug and secure spot for your bedding. Daisy chains, ice axe straps, and the Stow On The Go trekking pole loop make it easy to load up on technical gear, and side compression straps allow you to cinch down your load so you don't feel like you're about to tip over as you balance beam your way across the river on a fallen tree.
