WUQID Protective Silicone Boot Sleeve for 12oz-40oz Hydro Sport Flask/Stanle Water Bottles Tumbler Anti-Slip Bottom Sleeve Cover for All Water Bottles Bottom Width of 2.83&3.56in

It fit on the bottle, but the silicone is very thin. I don't think that it will last a long time. I already own 3 original boots for other HydroFlask bottles, and they are a way better and much thick, and they are cheaper than this one. The only reason that I bought this one instead of original Hydroflask is that i can't found online original Hydroflask boots. I'm a bit disapointed

Fits perfect on my TAL 40oz water bottle. I just want to know how you're supposed to put water for a pet in it when there is a drainage hole on the bottom. Just curious? ☺ That being said, I love it!

The pink one is very transparent, if you have a dark bottle it will definitely dull the colour. I won’t be using it but somebody might like it. Pretty sure it’s also not Hydro Flasks brand.

I bought this to fit my Owala bottle to protect the bottom and it works great. It was a tight fit to get on but once on its there. Loved that it was a 2 pack so I was able to put one on my child's Owala bottle as well.

Just over two years ago, I bought my first ever hydroflask. I saw people buying these "boots,", including a few friends of mine so I bought one. Firstly, the boot fit like a glove on my 32-oz hdyro. Secondly, I still have it on my hydroflask to this day. It has held up pretty well everywhere I've taken it. Seems to do well in the dish washer whenever it needs cleaning as well. Thirdly, I'd say it has prevented damage that could have been done if the boot was not on. I recommend!
