This backpack-style cooler fits up to 24 cans, making it a breeze to fill up and take on short hikes or picnics. The bag has freezing gel embedded inside, so instead of using separate ice packs, just fold it up and stick it in the freezer the night before your big adventure. It's ready to go when you pack it the next day and will keep contents cold for more than 3 hours.
