KUFUNG Tumbler Lids Spillproof 30 OZ, Splash Resistant Lid for Tumbler/For Yeti Rambler/Coffee Mug and More Cooler Cup (Black, 30 OZ)

Fits 32 ounce Hydro Flask thermal tumbler. The lid that came with Hydro Flask does not close. This new lid fits snug and does not leak!!

I like that it is leak resistant. My cup moves around but my coffee stays inside. Not for putting in your lunch bag unattended. Lid will pop off. (Common sense )

The lid does everything it's advertised to do. My husband broke the lid on on one of our 30oz tumblers so I bought this replacement with the flip top. It seals really well, no leaks. However his complaint is that it doesn't flatten enough against the top of the cup so when you drink out of it, the flap touches his nose. I tried it out and found the same issue. Because the seal was really good, we are buying the slider type from this same seller.

So nice to be able to replace the lids but not the cup

These lids were sturdy and fit my “Beast” 30 oz. tumbler but my steel straw didn’t fit in the top. Had it mentioned that it couldn’t accommodate a straw in the description I wouldn’t have purchased them in the first place. I returned them.

Fits perfectly!! The tab is somewhat difficult to push down, but it is definitely leak proof and has a good seal to prevent any liquid spilling out.

Product description indicates 3.5 inches. I measured 3.674. So almost 2/10th of a inch larger. The size description for a 20oz and a 30oz are the same. I was really hoping this was a solution.

I love them. They fit our Ibex tumblers perfectly
