WUQID Protective Silicone Boot Sleeve Compatible with 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

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!

These sleeves are the perfect fit for my wife’s and mine Hydroflask 40oz all around travel tumblers. The 2 pack was a decent deal and they work as they should and fit securely. My son saw them and is going to get a set as well.

Crazy thing: I purchased a black and a military green silicon boot for a 20oz tumbler from HydroFlask. The black boot fits perfectly. The green boot is way too large despite being the same size and model. I returned the green one. The black one fits better than the Hydro flask silicone boot for a cheaper price.

It is hard to put this on my 40oz Stanley. I’m not sure if it’s not meant for it or what but my boyfriend had to put it on there and I can’t get it off.

A couple of my Stanleys have started scratching on the bottom due to being placed/slid across rough or hard surfaces. I love this because it adds a layer of protection and now it's quiet when being sat down. It was super easy to put on and still fits in my cup holder. This one looks perfect and now if any of my coworkers buy the same one, it's super easy to tell them apart. 10/10

Great quality and worth the price

I needed a pink boot for my owala and they kept selling out on online so figured I'd try this brand. It fits really well and the color matches the pink of the handle perfectly tying it all in. Very happy with my purchase

Thought i cracked the code and found a cheap boot for my Owala, but it’s too big. When you pick up the bottle it just falls off. Stick with the name brand for Owala i guess

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

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.
