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 David Dreher

These great water bottle pockets. I think they would be good for walking or feeding pets. Also, we will fill one with water and leave it in the car. Great emergency water tank. The only downside I've seen is that it's inconvenient to pour from a faucet. There is no vent, so it must be filled slowly at first, otherwise the water will simply run back through the top side vent. It is made of medium quality transparent plastic. I bought them for my elderly mother. It's very easy to carry around.
