Works perfect with my Cool Vibe water bottle!
If you have a hydro flask, this flip top lid is a must. I have the Cool Vibe water bottle and it fits perfectly. I wasn’t a fan of having to unscrew my lid every time I wanted to have a drink. This thing is a life saver! Comes with a straw and everything. I’ve already bought 5 of them.
