Hydro Flask Tumbler Boot – Bottom Protector Sleeve – Silicone Tumbler Accessory Medium Black

This tumbler bot fits perfect and snug on my 40oz hydroflask and the color matched perfectly!

Love these boots for the hydroflask. Easy to install. Provide wonderful longlasting protection. Great price point to safeguard your water bottle

Matches the hydroflask in the Trillium color perfectly Had to work a bit to get it on the tumbler but then it fit perfectly. I use my tumbler for water only and hand wash it. I think you need to be careful to avoid any kind of mildew build up if you let water seep between the cover and the tumbler when you wash it.

Good little addition to my hydro flask. No loud clunk every time I put the flask down. Add's a little bit of width but still fits in my car cup holder.

This will NOT fit a standard, straight, wide-mouth Hydro Flask bottle. It will fit TUMBLERS only in their respective size. I purchased this from the "Frequently Bought Together" on the 32 oz wide-mouth bottle page. Waste of time and money. It did not say "tumbler" anywhere on the item page. Spoke with the manufacturer to confirm. The proper bottle boot for the wide-mouth is currently sold out so I don't have an option except choosing from a third-party manufacture where the colors won't match so I'm SOL.

Fir my 40 oz hydroflask perfectly. The color is an exact match to the color of my tumbler.

Works as expected good boot

I’ve had this around a year, it’s held up well and I think looks fine. My wife gave it to me because she didn’t like the color (it’s a pretty saturated blue, true to the product images) it does clash a little with my slate blue tumbler that she also gave me, but who cares it’s just a boot. Her loss is my gain!

Boot is great but didn’t fit my wide mouth bottle - didn’t read carefully!

Photos and description doesn't mention that it has a big hole at the base, although the product has quality.
