Mainstays Kids 14 oz Insulated Water Bottle vs Munchkin Stay Cool Insulated Kids Bottle

Buy the Mainstays Kids bottle for a school-age child who wants a bigger, one-button sipper that holds temperature and survives the dishwasher. Buy the Munchkin Stay Cool for a toddler or preschooler who needs a spill-proof valve and a soft straw. The Mainstays has the larger 14 oz capacity and double-wall insulation; the Munchkin has the leak-proof valve and a semi-transparent body that shows how much is left. Owners rate both well, with the Mainstays slightly higher on fewer ratings.

• Choose the Mainstays Kids bottle if your child is past the toddler stage and you want a bigger, insulated bottle with a one-hand push-button lid.
• Choose the Munchkin Stay Cool if you need a spill-proof valve and a soft straw for a younger child who tips and drops bottles.
