When we Osprey endeavored to bring a hydration reservoir to market, they knew it had to be groundbreaking in all respects - carrying water should never compromise fit, comfort or stability in a pack. The Osprey Hydraulics™ reservoir (2L/3L) has set a new standard in hands-free hydration and there's been no looking back. Combined with excellent reservoir-to-pack integration, superior technical features and the best gender specific pack-to-body fit and performance available, our hands-free hydration program takes yet another giant leap
The 3 Liter reservoir holds 100 fl. oz. of liquid and weighs 11 oz. Drink tube included. 16 x 7 x 3".
