This is my second Thermoflask. I love the color, design, and the way it keeps liquids cold all day. I also like that there are 2 choices of lids.

Nice size for my son to use in school. The flexibility of having a straw lid and a chug lid is great.

Great product. I am so amazed with the ThermoFlasks ability to either keep beverages cold or hot for such duration.

Absolutely love it keeps my water cold all day and can refill it at least 3 times without adding more ice to it

I love it, even bought my mom one. It keeps my beverages cold for hours, even without ice. Wish they had bigger sizes...

The color is beautiful and it works SO WELL. After a 9 hour shift, my iced drink still has some ice (I really need to drink more water....)

Absolutely the best product that I have bought so far. This product was recommended by a family member and it's worth every penny.

It keeps water ice cold for 36 hours. I've gone through 10 other water bottles trying to find the best. Thermo Flask is the winner for me.

I love these so much that I bought them in all of the colors they had. They keep water really cold, it lasts all day.

I bought this recently for my dad! He loves it so much. It keeps his water cold all day while he works :)
