Upgrade 2PCS Protective Silicone Boot Bumper for Stanley Quencher Adventure 40oz 30oz IceFlow 20oz 30oz Tumbler, Water Bottle Bottom Sleeve Cover Accessories for Stanley Mug Cup(Light Grey)

I got orange for my Twilight color Stanley, I love it! It fits great and makes it look better. No more metal sound when I place it down. Woo hoo! I think it’s worth the price, comparing to the actual Stanley ones.

Stays on!!! I purchased a different one that was half the size and it continuously falls off when I put it in/out of my backpack. This comes in/out of my backpack and stays on! It has really helped with protecting my bottles from clumsy drops as well as staying in one place on the table. I plan on buying one for each of my bottles. They fit snuggly but are fairly easy to remove (even with arthritic hands). They come in so many colors, I can't imagine not being able to find the color you want.

Fits my travel mug perfectly. The color matched my cup and there are easy to take off and clean.

Love the hole in the bottom, it helps get the cover on. I like how it stops the loud clang when I set my cup down. Fits in my cup holder.

I love my cups (non-Stanleys included) but I hate the noise the metal makes when you set the cup down. These are almost an essential for me - like a cellphone cover. It protects my cups and whatever surface it might land on. It fits snuggly and I intend on buying more in the future. I color-coded mine to show my support for my UNC Tarheels!!! Go Heels!!!

I was looking to protect my 40oz Owala and a generic 40oz cup I was gifted and these worked wonderfully! The darker purple color is exact to the picture shown and the material wasn't thin, it was sturdy and well made. Slid onto the cup easily but not off easily. Cup STILL fits cupholder in my Nissan Altima, albeit just a little tighter. I took away one star because this protector could be just a half inch bigger vertically and I'd rate it higher, but the current size didnt affect its performance thus far. Cup also didn't slide on and off a table so easily with this rubbery base. Would buy again and recommend, especially for two at this price!

Love the color. It matches perfectly and fits it perfectly.

Ideal for protecting the base of children's water bottle, providing stability. I recommend it. This fits 20-ounce bottles and fits perfectly.
