These bags have never disappointed me. I’ve never had a leak, and they stay just as cold as they say they should! Only reason I’m parting with them is because of a new set that was gifted to me. Beautiful eggplant color, zippers are solid and tight, minor wear to be seen if any, + bonus zippers on front of bag for all your small necessities like keys and lipgloss ;) If one was looking for ‘can’ size, the small would be a 6-pack (I used for lunch all the time), and the larger would be 12 to 18-pack depending on what you’re carrying.
