Review on Nefeeko 18oz Collapsible Water Bottle - Portable, Reusable Silicone Foldable Bottle for Travel, 💧 Gym, Camping, Hiking - BPA Free, Leak Proof, with Carabiner - Ideal Sports Water Bottle by Sam Lund

My wife and I bought these for air travel and I think that's the best use for this bottle. We top up our previous security and avoid exorbitant water prices. Several buyers have noted that it does not stand on its own or wobble when filled or partially filled. That's largely true, but knowing that it doesn't detract from its usefulness and ours will sit in our backpack pockets until needed. or staged demonstration. Don't hold the bottle by the neck and expect it to overflow; Take it closer to the middle or below. This is the reality of the folding bottle. Roll up the bottle as you go. Simple, but maybe not simple enough for some.
