Vmini Protective Silicone Boot, Compatible with Hydro Flask and More Water Bottles, Anti-Slip Bottom Sleeve Cover 12-40 oz

I wasn’t sure if the Vmini boot (Cobalt) would fit my Thermoflask 40oz from Costco, especially since Thermoflask doesn’t sell their own protective boots separately. That means if you want to protect the base, you’ll need to go with a third-party option—and this one delivers. The fit is surprisingly perfect. It slides on snug and tight, no slipping or gaps. The silicone feels durable and adds a nice grip on surfaces, which helps prevent accidental knocks or dents. Plus, the cobalt color adds a clean, stylish contrast to the flask. If you’re looking for a simple upgrade to protect your investment, this boot is a solid choice. Even though it’s not made by Thermoflask, it feels like it was.

Good color & fit

Fit perfect on bottom of 32 oz bottle. Was compatible with Hydro Flask. Seems a good quality and grips bottle firmly. Will come off bottle for cleaning.

The rubber boot fits well after having it for awhile now and hasn't broken down.

Bought this because my water bottle is pretty dented on one side of the bottom’s rim-I was hoping it would stabilize it. While I’m happy this bumper fit on my 40oz takeya bottle, it didn’t remove the wobble. Improved slightly, but probably would be better if the silicone was thicker/sturdier. If your water bottle is just *slightly* dented or chipping paint, will likely be helpful. The clear style bumper makes it so you can still see your water bottle stickers tho :) Happy I didn’t have to sacrifice my cool stickers for a little support :)

The only one that fit my Owala SmoothSip Slider 20oz. A little loose in the bottom but tight enough at the top so it doesn’t come off. Will fit the FreeSip Sway too but a bit hard to put on.

I have a hydraflow hybrid 25 oz and this fits well. Not so tight I can't get it on but stays secure once it is on. Does its job protecting the base and keeping it quieter when setting it down.

Good fit and keeps my Bubba from getting banged up

Works as advertised, it will keep the bottle from sliding and possible dings.

Quedó perfecta en la botella y se ve buen material

Fits good. Two thumbs up 👍.

I drop my hydro flask so much and this has saved it from dents

Fits the 32oz Brita Stainless bottle perfectly!
