BUILT 24oz Shasta Stainless Steel Tumbler with Leak-Proof Flip Lid and Silicone Sleeve

Tossed it in my gym bag sideways and nothing spilled. The flip lid snaps shut with a satisfying click and the silicone sleeve keeps my grip secure even with sweaty hands.

I've owned a few tumblers in this price range and this one beats them all. Ice water stays cold well past lunch, the 24oz size means fewer refills during my shift, and the sleeve dampens the clunk when I set it down on my desk. Cleaning is easy too since the lid opens wide enough to actually scrub the seal. Zero regrets at $11.

Keeps drinks cold for hours and the flip lid genuinely doesn't leak. My only gripe is the straw hole is a bit tight for wider straws, but the included setup works fine.

After my first one survived a drop on the driveway without a dent, I ordered three more for the kids. The sleeves come in different colors so nobody argues over whose is whose. Great tumbler for the price.

Does the job for commuting. Lid occasionally collects condensation in the flip mechanism, and it doesn't keep drinks quite as cold as my pricier brand-name tumbler. Still a solid budget option.

The base actually fits my car's cup holder, which my old 30oz tumbler never did. Sleeve texture is nice. Wish it came in more colors.

Loved it at first, but the flip lid hinge snapped off with normal daily use. Coffee stayed hot and it never leaked while it lasted, but I expected more durability.

Solid tumbler, no leaks, great price. Buy it.
