Review on 🥤 Premium Collapsible Water Container Bag by SurVivv - No-Leak, Freezable, Odorless, Flat Folding, BPA Free Food Grade Clear Plastic Storage Bottle for Sports, Outdoors, Camping, Hiking, Backpacking - 1.3/2.6 Gallon by Matt Jenkins

Large pockets. I use them like regular water bottles for carrying around, sharing water with others at parties and I love that you can deflate the bag and they can take any shape they need to fit in your fridge fit. You can write on the bag with a marker. The bags seal air and oxygen-rich water inside. They are very versatile for individual needs. MOST IMPORTANTLY, they are strong and appear to be flexible strong. The only downside is the plastic edges are rougher than I would like.
