Great for kids
[This review was collected as part of a promotion.] Excellent size for my toddler to carry on her backpack

adding to the collection
[This review was collected as part of a promotion.] This isn't my first one, probably not last either. Everyone in our family has a wide mouth bottle (kids get 12oz, which is perfect). And the different colors let us all have our own and we never confuse bottles. I personally hand wash all our Hydro Flasks and have never had any issues with the color coming off or fading.

Perfect
[This review was collected as part of a promotion.] My son is 4 and his name is required on everything. I engraved his name on his bottle and it's so neat, legible, and permanent.

Adan’s “big kid” water bottle
[This review was collected as part of a promotion.] Perfect size and color for my great nephew. Bigger than a mini and not as big as a 24 oz or 32 oz. Fits in his bottle holder on his bike and in his backpack.

12 oz Kids Wide Mouth Bottle (pink with yellow lid)
[This review was collected as part of a promotion.] Granddaughter chose the color. She wanted a Hydro Flask like her Mimi’s, only her size. She loves it and will no longer use any of her other water bottles. These are the best for keeping liquids cold for an extended period of time.

Perfect little bottle for my little!
[This review was collected as part of a promotion.] My 2 year old loves having her own little water bottle at daycare with her name easily found on it. The boot helps to keep it from denting as she drops it often. I love the color combo! Bright and subtle.

Straw doesn’t stay in place
[This review was collected as part of a promotion.] The straw on the lid does not stay in place. It moves while you are drinking, and then liquid does not come out.

Dented with first drop
[This review was collected as part of a promotion.] I’ve tried lots of different brands of insulated cups and I’m sad to say this one was dented after just 1 day when my baby knocked the cup over. I’m pretty tough on my tumblers of other brands and none of them have dented so easy.

Hello, we bought two of these bottles for our boys about a year and a half ago. The gray silicone part on one of the lids fell out. Is it possible to purchase a replacement for this part? Thank you

Hi! I purchased this bottle and the little gray (silicone?) part that prevents spilling has come out. Is it possible to get a replacement of this part? We LOVE this bottle and are so sad this piece is gone!

Does the straw lid have an actual straw that extends down into the bottle, or is it just an extension off the top?

Kind of silly but what is best to write their name with on the tag? I used a sharpie but it rubbed off turning it black (talk about disappointed kids). Then a pen over that but same thing. Thanks!

I bought a kid's wide mouth by accident, didn’t look at details, says not for hot beverages…any reason it can’t be used by adult for hot drinks with wide mouth flex sip lid?
