HEYSKAYProtective Flask Silicone Boot Cover Base 12oz-40oz for Stanley Tumbler, Hydro Flask Water Bottle. Compatible with All Water Bottles with Bottom Width of 2.85&3.56in

I’ve purchased 4 different boots from this brand and they work well on my various owala bottles. Haven’t tried on other brands but they nicely fit my 21oz plastic owala, 24oz insulated owala, 20oz owala tumbler and 40oz owala tumbler. Easy to take off to clean but doesn’t fall off during normal use. Love that they quiet the metal when I set them down and add a pop of color

Fits my Stanley perfectly and I love the colors. It holds up and has not lost any color or pattern and I've used it now for over a month. Placing the Stanley on a hard surface is much quieter now.

Fits my 40 oz hydroflask perfectly. Colors are the same as picture. Very cute and coordinates well with dark blue bottle. Daily use for about a month so far and still looks brand new.

Always embarrassed when my water bottle with clang on the desk or my briefcase or anytime. This rubber cap keeps it quiet when I set it down and it looks super cute. Also makes my water bottle distinguishable in a group setting.Good quality, goes on easy fits perfectly, well-made and did I mention cute?

THis fits well a bit snug, It should be but had to wiggle it on. I love how thick the plastic actually is!
