This is a 4.7L bag, with many pockets- one being mesh, and two being for large water bottles (however, the pocket can be tightened to accommodate smaller ones). I am selling this bag, because I bought it on an impulse. I wore it out for about 3 weeks, and found that if just didn’t suit my needs. It’s in like-new condition and just needs a new loving owner that will appreciate its value, as it’s a beautiful bag with so much potential. Thanks!
