HidrateSpark PRO Smart Tumbler Lid | Fits only 20 oz / 592 ml Insulated Stainless Steel Smart Tumbler

Great form factor

I love this lid. I struggled with the chug one. I teach golf and drink a lot of water outside. I am at ejsgolf.com. I would buy this over and over!

Got as an extra

Great!

A nice add on to my Tumblr, while the other one is in the wash
