This was a great find. I used to use another tube that fit my Nalgene bottle, which I loved, but the Nalgene bottle didn’t keep my water cold.
I saw this advertised and bought it to fit my hydroflask bottle. I just got back from a hiking trip in Southern Utah, where it was over 100 degrees every day that we were hiking. This was such a great find - the hydroflask bottle keep the ice and water cold all day and the tube made it so easy to keep myself hydrated.
I bent the straw trying to set everything up, but it still worked fine.
I would definitely recommend this.
