Size: Height 40.0 x Width 24.5 Purchased from a used clothing store. There's a hole in the back padding, likely where a cooling system was removed. A mysterious bag with holes, unlike a regular backpack. It even looks like a face, and I've grown fond of it... Besides that, it's unique, with a mesh section and a storage section that can be separated. It can be used as a mesh backpack on its own, or as a small item case and carried as a second bag. Made of quick-drying material, so it's fine if it gets dirty or wet! Fishing, the beach, the pool, airsoft... it should be useful for anything. With the side adjustment strings, if you can incorporate this into your cyber-style fashion, you'll be a stylish emperor. Awesome. For those of you looking for something a little different.
