Must-have Lid

This is a great lid the finger-hole handle feels so sturdy and well built. Very simple and effective lid with straw. Tiny gripe, wish you didn't have to pull as hard to get liquid out. Doesn't take away from quality though, very content.

doesn't leak, even when it's upside in your work bag for an entire day (hypothetically:)

MiiR 20oz Wide Mouth and the Leakproof Straw

My son and I each got a 20z widemouth double walled water bottle from an auto manufacturer in a gift bag. Sleek, excellent temperature insulation, and easy to carry ( no leaks). I started using this for bike rides, taking in the car, at the pickleball court, and bedside overnight. I wanted a simpler way to drink from the bottle without unscrewing the lid. Yes this is a 1st world problem but one I resolved to take on. After searching Amazon and the mfg website the challenge was resolved when I found the Miir Leakproof Straw Lid at the Miir website. When the straw lid arrived it was put to use immediately. It holds the temperature and is something that ,even if I knock it over on my bedside table, doesn't leak. Try it you will love it. My wife was feeling left out of the Miir nirvana my son and I were experiencing so I got her a Miir 20z bottle in the cool Prismatic color. It matched her pickleball backpack perfectly and she is now part of our Miir groove. PS I don't actually use the included straw to drink from my new Leakproof lid. It works just fine, no leaks and all I have to do is lift it so the liquid is against the lid. It equalized pressure without leaking. Magic, Science, or something else but it is a winner !

Great lid

I love this straw lid! It doesn't leak, helps me to drink water throughout the day, and is convenient when you don't have two hands to unscrew and hold a lid. I only wish it came in more colors to match my water bottle.
