Review on Protect Your Water Bottle With Vmini'S Anti-Slip Silicone Boot- Fits Hydro Flask And More 12-40 Oz Bottles by Ian Krump

Works great, got the orange one. It is hardly transparent with solid coloring and is well made. Contrasts well with my blue flask. You can just barely see the Hydroflask name through it, but this doesn't bother me. Despite being made by Vmini it does indeed fit my 40oz hydroflask very well. I would be concerned about the fit if you owned a smaller flask, but I'm not certain about this. Also, to clear up confusion in these reviews. There is indeed a tiny hole on the bottom. This is not a factory error. This eliminates suction so that the boot will fit correctly. It in no way affects the utility of the product. There is also a tiny amount of space between the bottle and the boot around the bottom edges, which adds to cushioning. Highly durable, very protective, great price, highly recommend!
