You are probably familiar Thermos – the company has been making insulated products to keep food fresher, longer for over 100 years. Lucky for mamas and kiddos, Thermos recently launched a new line of cups geared towards meeting the changing needs of your little ones. The Foogo Phases interchangeable sippy cups are innovative and bring the best of Thermos to babies and toddlers.
About Foogo Phases
Each child develops their own unique feeding habits, whether she begins to teethe early or demands a larger capacity drink cup to tame her growing appetite. Foogo Phases drinkware features interchangeable parts that fit all other Phases cups including insulated stainless steel and plastic models. With interchangeable parts, Phases drinkware easily adapts to your child’s changing needs.
Interchangeable Foogo Products
The Foogo line features six cups and 3 tops that all work and fit together to make 24 possible cup combinations.
- Phase 1 – 7 ounce plastic and stainless steel cups come with a soft spout sippy top and handles for babies 6 months and older.
- Phase 2 – 11 ounce plastic and 10 ounce stainless steel cups topped with chew resistant sippy tops.
- Phase 3 – 11 ounce plastic and 10 ounce stainless steel cups with pop up straw top.
We have the 7 ounce plastic sippy cup and the 10 ounce stainless steel sippy cup and I am really impressed. The cups are very solid and easy for both my kids to use. The plastic of the sippy cup doesn’t feel or look like a typical baby cup. It has the look of glass but the durability of plastic – trust me it can survive many a drop on the floor. The material is actually called “Eastman Tritan copolyester”, which sounds kind of intimidating but is quite safe for little ones – it’s BPA free. The stainless steel cups use Thermos’ double wall vacuum insulation, and are also BPA free and contain only FDA materials.
Drinks Stay Safer, Longer
The stainless steel cups use Thermos insulation technology to keep your kids’ drinks safer, longer. That is a huge plus in our house. The Department of Food & Science at Cornell University did a study to compare Foogo products to other sippy cups. You can see the summary here, but this is one snippet that caught my eye:
After spending 20 hours at room temperature, the milk sample in Foogo by Thermos had only 1,000 bacteria per teaspoon, while samples in competitor brands had as much as 2.5 to 5 million bacteria per teaspoon. In other words, the milk samples in the competitor brands contained up to 5,000 times more bacteria than the milk in the Foogo by Thermos.

To Buy or Not to Buy
To Buy… Our Foogo Phases cups are my favorite cups for the kiddos. I love that all the pieces are interchangeable so you can literally build a cup to suit your child’s needs. They are dishwasher safe and the leak-valve is easy to clean. And, of course, you can’t beat the Thermos reputation and insulation technology.
Or Not to Buy… My only complaint is that the tops of the cups leak a bit. It doesn’t leak out of the neck of the cup and the cup spouts don’t leak, but if any liquid makes it through the valve it drips quite easily because the top is wide.

November 12, 2009are these dishwasher safe? stainless steel is tough because a lot of these aren’t dishwasher safe.
YES! Both styles of cup are dishwasher safe. And the stainless steel cup looks great after being washed – not streaky or cloudy like some stainless steel can look.
