This is a well loved, but still functional black Lululemon backpack with a lot of life left. Zippers all work great. 22L capacity includes two water bottles, a large open front pocket with a reflective strip for low-light situations, a large main compartment for most stuff and a separate zip section for a laptop up to 15". There are two mesh pockets inside the main compartment too. There's a zip-off front pouch that can be carried as a solo sling bag - I can't find it right now but know it's somewhere around in my house so I'll find it for you. I'm not sure where the chest strap clips are but I'll look for those too.
