CamelBak's super-light Charge 450 gives you enough water and carrying capacity for full-on epics without weighing you down. It's made from rip-stop fabric with water-resistant DWR coating and it comes with a huge 100-ounce Antidote bladder. Inside, thoughtfully distributed cargo space with internal organizers store your gear and extra clothing so you can ride all day without a pit stop. The Charge also boasts a sealed media pocket with a cord port and an XC helmet carrier. Plus, you get a feathery, breathable back panel and a supportive harness system, so this pack feels as great at hour six as it did at mile one.
