Made to meet most airlines' personal item policies, Osprey's Daylite Expandable 26L+6L Travel Pack is the perfect side-kick for our flights and outdoor adventure travels. The Daylite features a suitcase-style, full zip opening for easy access to the main compartment, which we can expand by 2 inches to add another 6 liters of internal capacity. It also includes a convenient organizer pocket with a key clip, a laptop sleeve against its backwall, a zippered external pocket that fits our toiletries well, a front shove-it pocket, and stretch side pockets to stash our water bottle and an extra layer. As always, Osprey has built this pack with high-quality, recycled materials that are certified for minimizing harm to people and the planet.
