I love this! I have it on my Hydro Flask and its a snug fit – no leaks! I also love that the mouthpiece is a hard plastic and not the rubber-ish kind that the Hydro Flask brand produces. I just feel like it stays cleaner and is easier to wash. I have a Hydro Flask flip top for another bottle and its shown bite marks and such… definitely not as nice as this, in my opinion. You guys gotta make these in the larger size for the wide mouth bottles!
