CoolCore™ keeps drinks cool without the clang! The double-walled bottle with a stainless steel interior insulates drinks to keep them at a tasty temperature. The outer wall with DropGuard protects the bottle from denting or other damage when it drops (or when your toddler tosses it) without the jarring clang of stainless steel hitting the floor. And the leak proof design means no worries about kids leaving puddles along their path. This toddler water bottle gives clean sips too thanks to the pop-up straw with a silicone spout that stores flat when not in use. A quick push pops it up for sipping. The handles give toddlers on the go an easy way to carry their drinks around, but remove easily when no longer needed. Featuring a sleek design, this water bottle is a great pick for older kids too who want a water bottle just like the big kids. Done sipping for the day? The water bottle is top rack dishwasher safe, and the covered pop-to-sip button means no worries about toddler's sticky hands getting goo stuck in crevices. Like all The First Years cups, this water bottle is made without BPA.
