Great Cap and Interchangeable TooThis is a great cap. I could not find my cap and noticed that my son had put it on his water jug (that was not a Hydro Flask) because he lost his. I ordered 2 more since they are interchangeable. Love them!!!

The OGNO DRIP! That’s all I wanted in a lid, and this is the only one that keeps my bottle safe!

Super cute!There’s a little rubber piece that popped out of my original lid and was causing leakage. So I just bought this one on clearance and it’s been good as new.

Back-up topBought this as a back-up top for my carnation 32oz bottle. I love the color, it fits great & the color contrast looks cool too. I try to have back-ups because you never know when you might need one. Quick shipping as always :)
