- SMShannon M.Verified BuyerRated 5 out of 5 stars1 month agoMy 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!
- ARAdrianne R.Verified BuyerRated 5 out of 5 stars5 months agoSports bottle for the win 🎉
Love this bottle it’s the perfect size. Fits in your car cup holder. I loved it so much that I bought one for myself. I purchased the green one as a gift for my daughter and I bought the orange one for myself. Keeps your drink cold and I have them in all different sizes so I always have one with me whether I’m at home or on the go.
- JWJustice W.Verified BuyerRated 5 out of 5 stars6 months agoUse for breastmilk!
I got one for myself 46oz and my daughter 18oz. I put our names on them. The bottles stay cold for days with ice! I keep breast milk in the bottle for my daughter. Better than using ice packs and baby bottle.
- PHPamela H.Verified BuyerRated 5 out of 5 stars6 months agoBest Water Bottles I've Ever Owned!
This is the 4th bottle I've bought. This one is for my husband, because he hears me talk about my bottles ALL the time! Me: "See my water bottle still has ice in it! (when everyone else has luke warm water). So he was like, I want one. And now we own 4 in all different colors and sizes. Obsessed with the colors too!
