Love it
I bought the Hydroflask and wanted the boot to protect the flask and surfaces. It is snug so it doesn't fall off and protects the surfaces any time I put it down. I highly recommend the Hydroflask boot for all flasks you get!

A bit pricy for a piece of rubber, but it's a good product
The boot protects the bottom of the hydro flask very well, and makes the bottle feel significantly more stable than the bare steel on inclined or bumpy surfaces.

Perfect Fit on 32oz Hydroflask
Fits perfectly on my 32oz hydroflask, and even has a teeny little hole in the bottom to relieve air pressure and make it easier to put on and take off. I really like it! It also has another purpose - it makes it quieter to set down on tables, which is nice!

Worth it
Works as described. Definitely nice if you like to set your hydro flask on top of the car like me. Side benefit: these will also (with some work) fit on a Nalgene bottle if you’re tired of them sweating all over your things.

Authentic Hydro Flask Boot
We bought our son a Hydro Flask and were having a hard time finding a boot for the larger size bottoms. Since he is a kid this has helped him to not dent the bottom of the Hudro Flask, he has had it for about 2 months. It also has protected table tops he sets it on. I don’t have to worry he is going to scratch a table top or desk. The packaging and markings matched our daughters pink boot we purchased separately from a brick and mortar store - therefore we believe it is authentic Hydro Flask boot.

Adds color and protection
Looks good and helps protecting the bottles from slipp, knicks n scratches. But be warned, keep it dry or it will start rusting.

Awesome!!!
Awesome product! Can’t believe I didn’t get this earlier. I’m rough with my water bottles and this seems to help. I also like how quiet it is now when I place it on my desk or counter top.

Does a great job of protecting. Also love the fact that it dampens the noise of when you put the hydro flask down or hit it slightly.

The HYDRO FLASK silicone Flex Boot Cover has a 72.0mm outer diameter uninstalled and fits nicely on the STANLEY 16oz Travel Mug (Trigger Action, or Neverleak). The fitment is agreeably tight, i like it very much. For the polar-white Travel Mug one should choose the white semi-transparent color because it matches the white finish of the thermos. My little sister prefers the pink color but i find it awful. In any case, the quality of the product is amazing and well worth the money.
