    Best of the best

    Water bottle that beats all others. Love this bottle. I love all the coldest bottles. I have 6 of them. Keeps water cold for days not hours. And the limitless with the handle is awesome. It comes with three different lids. And the accessories are the best I have seen. And so many coldest bottles that the cirkul lids fit. So it’s a win win on the coldest bottles.

    My son started with the 14oz bottle 3 years ago. After 2 years of school and being ran over, it was time for a bigger bottle! Even after I ran over it, it didn't leak! We love this company!

    My five-year-old loves it the color pink

    I bought this for my five-year-old she was starting school and she loves pink ! It’s the perfect size to fit in the side of her backpack is stays cold all day long for her. And she uses it at night time on her nightstand in case she gets thirsty. She does chew on the straw so I might have to buy another cap lol. but she loves it. So everyone in our house now has coldest bottle and we all love them!
