Parent FAQ

Which size is best for my kid?

6.7 oz is perfect for toddlers and preschoolers. 15 oz works for grade-schoolers and lunchboxes. 20 oz is great for active kids, sports, and full school days.

Are these bottles really leakproof?

Yes — every Coldest bottle uses our triple-seal cap. Toss it sideways in a backpack and your books stay dry.

Is the bottle dishwasher safe?

Lids are top-rack dishwasher safe. We recommend hand-washing the insulated body to protect the vacuum seal.

Do the colors fade?

No — every kid design is printed with a scratch-resistant powder coating that holds up to daily kid-life.

What if my kid loses or breaks it?

Coldest bottles come with a lifetime warranty. Reach out and we’ll replace it.
