For example, shop the Stanley Aerolight Transit Bottle to keep your drink cold from morning to night. Plus, the Contigo Aubrey Kids Water Bottle is cleanable, spill-proof and dishwasher-safe.

Best for little kids

"Parents of toddlers and preschool age kids know that finding the right water bottle is one of the keys to maintaining your sanity!" Bergamotto says. "This one from Contigo is easy for little kids of any age to maneuver, but also keeps liquids in the bottle (and not all over your little one or their bag!)."

Best for big kids

"As a mom, my favorite thing about this is that it's dishwasher-safe and extremely easy to assemble!" Bergamotto says. "My kids love that you can also customize these! A really great, useful gift that kids will love and parents will appreciate."

Best leakproof

"This has a push-button lid and carry loop that doubles as a lock," Bergamotto says. "That lock prevents spills and leaks like nothing else!"

Best multipurpose

"With nearly 50,000 amazing reviews, this keeps cold liquids chilled for 24 hours and hot liquids warm for 12 hours!"

Best for commuting

The AeroLight embraces convenience as it fits most cup holders; comes with a "locking, leakproof, drink-through lid"; and is dishwasher-safe.

Best value

"Simple Modern has become a go-to brand for affordable quality, so it makes sense you can pick this up at Walmart!" Bergamotto says. "At 32 ounces, this one is double-walled and insulated! It has a straw lid with a silicone mouthpiece, so the sips always taste pure."
