Lid needs a redesign.

I had an older version & the straw was much easier to flip up. It also didn’t have as much silicone in the lid, which is now growing mold because I can’t adequately clean there.
I really want to love this tumbler because of the flip straw & the ability to wash it in the dishwasher, but the lid needs a revamp.

No, I would not recommend this to a friend.

Doesn’t keep ice as long as expected. I bought the larger size because description said keeps ice for up to 3 days. I didn’t even get one day of ice
No, I would not recommend this to a friend.

Fits in Cup Holder!
on June 16, 2026

I’ve been a Yeti girl for as long as I can remember and I have been getting so frustrated that they don’t fit into the cup holder in the car!
These Stanley’s fit into the cup holder, and keep things cold for quite some time! Will be buying another!
