I left it outside with water and ice. It sat in the sun for well over an hour. I would say closer to two hours when I came inside removed the lid and there was ice still inside. So you tell me what I think of it. I highly recommend this tumbler
The tumbler looks great, works great, the lid fits well and it holds cold temperatures. Happy with the purchase and would buy again.
My grandson loved it. He slept with it the first night he had it. It is very well made and super cute. The one issue I do have is getting the lid off. It can be almost impossible. But overall it is great! GEAUX TIGERS!
Perfect addition to my morning coffee and afternoon protein shakes! Easy to clean, durable and stylish.
Held ice solid for 7-8 hours. Tops in ice retention //. Have NOT used with java yet. Looking forward to ☕
Great tumbler. The ice does not melt for many hours. I have 4 of different brands, they are now in the trash. This brand is phenomenal!!!! Buy some!!!
I love my new Penn State tumbler. It's sturdy and very attractive. It shipped on time and arrived on time. It was shipped in a protective box with added protection! I'm looking forward to trying it out!
