FlaskarsProtective Silicone Boot for 12oz - 40 oz Hydroflask Water Bottles Anti-Slip Bottom Stanley Sleeve Cover Bumper

Great fit and protection. Reasonably priced

Fits perfect on my hydroflask wide mouth

Definitely a hydroflask silencer! Love this, great material that I haven’t notice catch any lint or anything

I ordered the black boot for my Hydro Flask 40oz, and it wasn’t hard to put on. It stays on securely and seems well-made and durable. I needed this since I take it everywhere and don’t want to damage the bottom or scratch furniture. Not bad for the cost.

Does what the item is intended for which is protect the bottom when set on the ground or other surfaces & keeps your flask from sliding on said surfaces. Nothing more, nothing less. It adds to the look of the flask in my opinion. Only slightly irritating to remove the small particles off it due to the texture depending on what you use to clean/dry it with but overall it's nothing major. Definitely get one if you can, honestly it's a must. A1 product👌🏾🔥.

We bought this for our kid who uses several sizes for sports and school. She was careless with setting these down or even swinging them against our counter tops and so forth. We bought them and they fit great and she can set them down without banging anything. However, note having these on makes them difficult to slide into the side pouches of book bags and soccer/sport bags. It will go in but you have to really twist them in to fit. They won't slide in -- just small warning.

Works great for my hydroflask! I think it helps protect it from drops.
