Hydro Flask Flex Boot - Accessory Silicone Water Bottle Protector - Dishwasher Safe, BPA-Free, Non-Toxic

Fits well, and doesn't slip when coming out of cup holders (biggest gripe I had with non-brand name boots).

This little add-on makes a big difference. I bought the Hydro Flask Flex Boot to go on the bottom of my 24 oz bottle, and it fits perfectly. It adds just enough cushion to protect the base from getting dinged or scratched, especially when I set it down on hard surfaces. It also gives the bottle a little more grip so it doesn’t slide around as much, which is great for the gym or the car. The silicone feels thick and durable, and the color matched my bottle nicely. It’s a simple accessory, but it helps keep the bottle in better shape long-term. If you’re already invested in a Hydro Flask, this is a smart upgrade.

Works great. I drop my metal water bottle from time to time and this has prevented dents in the bottom of it.

I bought this for my son‘s Hydro flask, and it does not fit according to him. I did not try it on to see if it fit.

i love having these boots on my water bottle because it defends from dents and chipping from being on different surfaces. the color is beautiful. the quality is amazing.
