  • Does its job
Style: Medium Color: Black
Does what it is supposed to do. It was very easy to put on and fits the 40oz bottle nicely. Looks good and protects the bottle but also helps keep it quiet when I sit the bottle down. So far so good, looks like its going to hold up to my daily use.

  • Hole punched in bottom is unnecessary.. (update: it's necessary...)
Style: Small Color: Snapper
Update: Okay, I'll admit the hole is very helpful. My previous bottles have been powder coated, which doesn't create much suction. This new one I'm using with this Flex Boot is smooth metal, and it would have been pretty tough to put on without the hole. ________________________________________________________________ Original review: I own an older version of the bottle boot which has no hole in the bottom. Supposedly, this hole is to help release pressure when putting it on, but I think it was never a problem to begin with. The boot stretches, so it's pretty easy to get a finger in there to release pressure. I've never had an issue putting my boot on or taking it off. To me, this just feels like a damaged item that now has a hole for water to leak in. ... show more

  • Great protection
Style: Medium Color: Black
Fits perfectly on my 32oz Hydroflask. A bery small hole on the bottom of the sleeve make it easy to slip in the bottom of the bottle. Fits snug and stays on nicely. I remive when I hand wash. Protects bottom of Hydroflask from dents and chips. And yes, you will eventually drop it

  • Great Purchase!
Style: Medium Color: Black
This rubber boot is great for protecting your Hydroflask and the medium size fit perfectly on my 32oz bottle. The bottom piece is more structured than the sides and it has held up well. The only thing to note is that the black color is not the same as the black Hydroflask bottle lid which is shown in my picture. The boot has more of a blue hint to it. ... show more

  • Great Product
Style: Medium Color: Black
This is great to keep on the bottom of a hydro flask water bottle. It has already protected my bottle from getting scratched and dented, and it also protects my furniture when I have my bottle resting on the nightstand or coffee table. The fit is great and easy to clean. 10/10!
