30 oz. Stainless Tumbler SX-HA89H

Iced coffee still had ice cubes in it six hours after I filled it, which is honestly better than my old tumbler ever managed. The transparent lid actually does what it says — no splashing when I toss it in my bag, and the straw clicks in snug.

The splash-proof lid is the reason I grabbed this, and it does exactly what it says—no leaks even when I toss it in my bag sideways. Ice from my morning coffee is still clinking around at happy hour, which is wild for a 30 oz. size.

I’ve been filling this 30 oz. tumbler with iced coffee every morning and the ice is still clinking around at lunchtime. The transparent lid makes it easy to see when it’s time for a refill, and the straw fits snug enough that I don’t worry about spills in the car.
