WUQID Silicone Boot Sleeve Compatible with Hydro Flask Travel Tumbler with Handle 32oz&40oz and 12-24oz Hydroflask Bottle & Stanley 20 30 40oz Tumbler, Fit 2.83-2.95in Bottom, Anti-Slip Bottle Cover

I wanted to keep my new 30oz S’well mug and 40oz Cirkul Straw Sip mug in as perfect condition as possible. Also, wanted to quiet the noise they made when being set down on some surfaces. I searched locally but was unable to find any so I looked on Amazon. I saw tons of them that said they fit that very popular Stanley cup but wasn’t sure if they would fit my mug. I measured and was finally able to compare my cup with a Stanley mug. I took a chance and ordered one. It proved to be a good choice! It fit great and has kept my cups in great condition! The color and price were great also! Very happy with my purchase!

This fit my 40 ounce Hydro flask, Tumblr perfectly and matched the color perfectly perfect. It will protect the bottom of the Tumblr against any other surfaces like nice wood. The fit was perfect. The color was perfect. The functionality was amazing. The design is perfect. it feels very durable and I feel very happy with the value.

Fits perfectly and matches with my Hydroflask. But it did come dented (because it comes folded) and the dent does not go away.

Fits perfectly. Easy to take off and on when cleaning my cup. Love it being transparent. The silicone sleeve adds stability so I feel confident when I set it down. The price point is great also. I’d definitely buy again if needed in the future.

Works great and love the colors

this does not fit the hydro flask well. It had creasing from the packaging that wouldn't go away.

I bought the silicone sleeve so my Tumbler would not slip or scratch surfaces, or that my Hydro-flask would not be scratched. It fit perfectly and matches my pink tumbler color. I feel more comfortable using my tumbler with the sleeve.

This Hydroflask sleeve fits my 40oz Timber perfectly and helps with noise when setting it on a hard surface.
