Made entirely of PFC-free recycled bluesign-approved fabric, the versatile Osprey Daylite doubles as an ultra-lightweight 13 liter (793 cubic inch) daypack or a large pocket/removable "Add-On" daypack for compatible Osprey backpacks and luggage (sold separately). The pack's simple profile allows it to serve well as a backpack or luggage storage pocket, but a number of built-in carry features also make it a fully-functional daypack. A low-profile, tuck-away spacer mesh harness and removable webbing waist strap ensure comfort and a secure fit. A mesh covered backpanel provides support and ventilation. An adjustable sternum strap lets you dial in fit and includes an integrated safety whistle. A harness grab handle can also serve as a luggage handle pass-through. In addition to the large panel-loading main compartment, there is a zippered front pocket with built-in organization and a key clip, side stretch mesh pockets, side compression straps, and a padded internal sleeve that can accommodate a hydration system or a 13" laptop or tablet. The Osprey Daylite is available in your choice of color options.
