Hawsaiy 12oz Kids Insulated Water Bottle vs Mainstays Kids Insulated Water Bottle

Both are small double-wall stainless bottles for kids with one-button lids, so the choice comes down to size, lid type and cleaning. The Hawsaiy holds 12 oz, has a straw lid with a sliding lock and a visible carry handle, and a much larger review base at 4.7 stars. The Mainstays holds slightly more at 14 oz, has a chug-style auto lid and a hidden handle, but it is hand wash only and has far fewer ratings. Buy the Hawsaiy for younger kids who sip through a straw; buy the Mainstays for kids who prefer to gulp and need a bit more capacity.

• Choose the Hawsaiy if your child drinks through a straw and you want a locking lid plus a bigger pool of owner reviews to judge it by.
• Choose the Mainstays if your child prefers a chug lid, needs a little more capacity, and you don't mind hand washing.
