Whether the journey calls for trekking in Nepal, traveling Europe by train, or backpacking in Yellowstone, the Osprey Mens Waypoint 80 backpack is a do it all workhorse for worldwide adventure. An ideal capacity is 50-55 pounds, a substantial amount when compared to the carrying capacity of other travel backpacks. The Osprey Mens Waypoint 80 backpacks ability to carry heavy loads is largely due to an advanced suspension and harness system, very similar to the system used on Ospreys highly regarded mountaineering backpacks. Peripheral composite rod suspension stabilizes the load and transfers the weight to the gender specific built-in IsoForm hipbelt and interchangeable shoulder harness. Most people find that the shoulder harness size included with the backpack matches their needs. A Spacer Mesh foam backpanel keeps the air circulating between the pack bag and your back, and efficiently pulls moisture away from your back. Both the shoulder harness and hipbelt on the Osprey Waypoint 80 mens backpack stow behind a protective cover for carrying as a duffle bag or preparing for airline, train, or bus transport. Other luggage characteristics include a panel loading main compartment opening with a lockable 10 YKK zipper, very similar to the construction of most suitcases, plus foam stiffened sidewalls, and a luggage style side carry handle. For short excursions, a 600 cu. in. daypack detaches from the main backpack, or when attached it can be used as a large pocket for organizing big loads. Additionally, the Osprey Waypoint 80 backpack has internal fabric and mesh organization pockets inside the main compartment and exterior stretch mesh side pockets for quick access to a water bottle, camera, or snack.
