I L O V E this water bottle. It fits "softly" in my pack and collapses down to almost nothing when empty. You can even put it in your pocket. Super easy to deal with. One suggestion I would make is a loop to hook it to my belt.

The material is very durable. I love the fact that they can fold up when empty. 2 filled bottles is the perfect starting weight for my 40 lb pup.

I was previously carrying water in a Nalgene but it was too heavy to carry around all day. This is perfect and it doesn't drip or leak at all. Actually I threw my book in right next to this water bottle and it didn't get wet.

I saw these in a hiking harness and thought they'd be perfect for adding to my dog walking pouch (a converted media crossbody). I got two since they're being discontinued. My dog drinks directly from it, and it's just the right size and weight to carry around until she's thirsty.

Since it’s so flexible I can squeeze it between my dogs chest and swamp cooling to wet the inside easily while on trail
