The 40-ounce travel tumbler performs exceptionally well, especially in extreme heat. On the day I received it — with temperatures hitting 105 degrees — I filled it with ice and iced tea. After finishing the drink, plenty of ice remained. The tumbler then sat in my vehicle until late the following afternoon. When I opened it more than 24 hours later, most of the ice had melted, but several solid chunks were still floating. Its insulation clearly lives up to the claim of keeping liquids cold for 30 hours.The tumbler holds a full 40 ounces and features a heavy-duty plastic exterior that’s BPA, lead, and phthalate free. The inner chamber and straw are made from food grade stainless steel, and the screw on cap creates a reliable airtight seal. I noticed no sweating on the exterior, and the outer casing of the cup stayed at room temperature despite being filled with ice.I ordered the cloud blue version, which includes both a leak proof sipping spout and a stainless-steel straw with a cleaning brush. The handle is comfortable, and the tumbler fits easily into my vehicle’s cup holder. While I only tested cold retention, its performance suggests it should handle the advertised 12 hours of heat retention without issue.Overall, this is a durable, well-designed tumbler that excels in real world conditions.

Love it!

Purchased this for myself and my daughter ended up stealing, err, I mean using it for herself. I wanted it to use while I worked out, the 40oz, I felt like, would fit the perfect amount of water I needed.For my daughter though, who only drinks water, this is perfect for her. She can put cold water in it at 7 in the morning with a few ice cubes and it'll stay cold for her all day while she's in school. The handle is easy for her to keep a firm grip and the tumbler itself isn't too bulky for her smaller frame.I switch out the straw with a plastic one because the steel one just doesn't make sense to me, I feel like it'll easily rust and I don't want those problems!Overall, it's a great tumbler that effectively works to keep your drink cold...or hot, depending on your preference.

I did a lot of research before ordering this tumbler and I’m very happy with my decision to order. I love that the straw is stainless steel instead of plastic and it’s made from high quality 18/8 food grade stainless steel. It keeps my drinks ice cold for hours, doesn’t leak and fits perfectly in my vehicle’s cup holder. The handle makes it easy to carry and it feels sturdy and well made. If you’re looking for a durable tumbler with thoughtful design and quality materials, I would definitely recommend this one!

Drinks and ice can satay cold for up to 72 hours

absolutely love this tumbler. The lilac color is beautiful, and the 40 oz size is perfect because I don’t have to keep refilling it all day. It keeps my drink cold for hours, fits in my cup holder, and the stainless steel straw is a huge plus. I also love that it’s leakproof and made without lead, BPA, or phthalates. This has honestly become my go-to cup every single day.
