Description:

Osprey decked out the Mantra 30 Hydration Pack with all the thoughtful features that grace the rest of its Mantra series, and built the pack in a large 30-liter size for epic day hikes and super-lightweight overnighters. An included 3-liter water reservoir holds all the water you need for a big day, and the straw rests on a magnet at the sternum for easy access. A rotating bite valve makes it simple to reach down and guzzle some H20.
