Great lid - should be the default

Love the finger hold for carrying and picking up the bottle. Seals well and keeps liquids (water) cold. Easy to remove and clean.

Leaks a little

I purchased this lid because the one I had on my 16oz cup the seal was damaged and it was leaking. I didn't see on the website where I could just purchase the seal. I like this lid because it has a handle & straw that folds out. It does leak a little in the fold of the straw though.



While we don't have replacement gaskets available for purchase on our site, they are always covered by our lifetime warranty. If you are experiencing leaking with your lid, that is also covered under our lifetime warranty. Send us an email at hello@miir.com and we'd be happy to set you up with some replacements!

Leakproof Straw Lid

Love this lid!!! Our whole family has one of these lids because it’s excellent to take to a ball game, walk, park, picnic etc… You can carry it by the loop, you don’t have to open the whole lid to take a drink which helps with contamination issues etc!! It’s great!!

Works great, but just make sure you remember to open it slowly if you put carbonated or hot liquids inside.
