Customers love this travel mug's flip-up straw and its ability to keep drinks cold for up to 24 hours, with one noting it doesn't spill when the straw is down.

Great Cup! Excellent Value

Melissa B.—January 15, 2026✓ Verified purchase

My dad really loves this cup other than it is a little heavy for him to lift, but he is getting used to it. He loves the fact that it keeps his water cold for a long period of time and he doesn't have to get ice as often. Excellent quality, love the color and very durable. Read more

Great functionality of this sip straw leak proof lip and of course yeti quality and I really like the 40 ounce with handle dimensions, bought again already in a different color, hoping yeti brings more colors for this size and model! Read more

awesome pick

I usually use Stanley’s, but I’ve been experiencing mold problems with those so I switched to this yeti and I LOVE it. Stays cold for so long. Fits in the cup holder, I love the red color it’s vibrant and beautiful. Easy to clean, leak proof doesn’t spill when it tips over, amazing! Highly recommend. Worth the price. Read more

Works but came scratched & not looking as expected.

Julie W.—December 10, 2025✓ Verified purchase

The plus side is it doesn’t leak like the Stanley and keeps cold for many hours. The product is good and works. It did not arrive as expected. It came scratched up and is too much trouble to send back. It also does not have the white flip top. The picture is deceiving. If I wanted gray anywhere on it I would have ordered gray. Read more
