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

I got this silicone boot to protect the bottom of my new DeWalt 30 oz tumbler. I got the Gangster Armor Grip silicone handle and it came with a silicone disk for the bottom of the cup. However, it still left the whole base subject to dents and dings. Those don’t make me happy. So, I was thrilled to find this one piece boot that covers the entire base of the tumbler.It came in a vacuum sealed bag. Unzip it and your boot pops open and back to life. I had no problem sliding it onto the base of the tumbler and slowly worked it all the way up. It’s tight and secure. It assists by reducing possible slipping and its material makes it a little harder to tip over. I recommend this item. So far, I’m very pleased.

I got the Fog color cup so I bought the chambray one ro go with it. The color mayches perfectly and it was very easy ro put on. It fits snug.

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!

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.

When I bought my 20 oz IRON FLASK bottle, I forgot to get a boot for it. I didn't want to spend $12 (incl. shipping) to get one, just to have the brand name on it. And since I had another bottle that needed a boot, I figured why not go for this--$10 for 2 boots. I went with black.The fit is excellent. I could be just a little bit tighter, but it does hold well enough and if you want to remove it the effort to slide it off is fairly easy. The good thing is that the boot is long enough that it won't accidentally come off under normal circumstances. However, if you're going to use this for a travel bottle and might be pulling from a pack frequently, you might want to line the inside surface near the top with a little grip tape.The quality of the silicone is really good. It has a slight velvety feel, but not a tacky rubber quality as you might come across with cheaper silicone. I think this should last a good long while.

Fits great on my 30 oz, Stanley.

I love that it protects the bottom of my cup from scratches.

I know it’s silicone so it’s bendable, but it sure came in all bent and it’s not shimmery like in the picture at all. For the price, it’s not so bad. It’ll still get the job done. Still disappointed but not worth returning.

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.
