Patagonia Atom Sling 8L Navy Retail Price: ¥9350 Purchased the year before last, used approximately 10 times in total. There are some marks on the sponge of the back and some dirt on the side of the back, but I don't think it's that noticeable. Whether by bicycle, on foot, or by bus, its moderate size and organizational features make it easy to carry anywhere, and its sling-style design fits snugly and comfortably against the body. 8-liter capacity. Made in a Fair Trade Certified factory.
