Out of Osprey's Archeon collection of daypacks and trekking backpacks, the Archeon 25L Backpack is by far the most versatile for life on or off the trail. It's the smallest of the bunch, and best-suited for casual hikes and everyday life. Osprey made it out of completely sustainable fabrics to be a little nicer to the planet we all love to explore. Recycled nylon canvas covers the entire pack for long-lasting durability as well sustainable efforts. Two aluminum stays and a framesheet offer plenty of support when you're on a long trail, and padded shoulder straps work with the seamlessly padded waist to keep you comfy from first mile to last.
