HYDRO CELL Silicone Bottom Boot - Protective Cover for 64oz, 40oz, 32oz, 24oz, 18oz, 14oz Stainless Steel Water Bottles, Anti-Slip Insulated Bottle Protector Accessories

The prevents the feel that you are going to bang on something or scratch up your bottle or the surface you are placing it on. The color match is just right and stays on tight enough that you don't feel like you are going to lose it -- but also is easy enough to remove for cleaning.One drawback: The boot does make it harder to insert and remove the whole bottle into/from a backpack netted pocket. I tend to remove it for that and just toss it into the pack.

great bootie for my 40oz bottle it slides on very easily and stays on and i no longer hear the metal clang when i put my bottle down

I ordered the 24oz and it is way too big for my water bottle which is a 24oz bottle. And it is the same brand so I don't know what the problem is. I ordered another one for my 32oz bottle and it fit nice and tight but the one for my 24oz is way too big so if you lift the bottle the sleeve falls off and does not hug the bottle tight. It does not fit tight like my other one. Must be defective?UPDATE: Hydro Cell contacted me and I discovered that I had ordered the wrong size boot for my water bottle. I thought I had a 24oz bottle and I actually had a 18oz bottle so I re-contacted them and explained that I had made a mistake and they were really helpful and together we solved the problem. Their customer service is so accommodating and helpful and products are great. I will definitely be purchasing from them again!! Changing my rating to 5 star from 3 star!

My water bottle was always clunking loudly when I set it down so I got this to help with that and also prevent denting on my new bottle. It fits nice and snug and works as it should.

I like this -- it's pleasant to touch, it fits the bottle well, and it does a good job keeping it upright.Unfortunately, when it comes to cupholders, this thing turns what is already a poor fit into an impossible one. So you'll have to either get used to removing it all the time, or to not using cupholders.
