This Osprey Waypoint 80 travel/hiking backpack, with a 65L main pack and 15L detachable daypack, is an out-of-production workhorse that is ready for your next adventure. It's like a beefed-up version of the Farpoint/Fairview line. The daypack zips and buckles securely to the main pack, which is equipped with Osprey's load-balancing internal frame. In excellent condition with everything in perfect working order. I measure the dimensions at about 27 inches tall x 12 wide x 16 deep.
