The water bottle holds 16 ounces and is made of durable plastic, which is BPA-free and sturdy enough for kids to take anywhere they want. When it’s not being used, just cover the comfortable silicone spout to keep it clean; it opens easily (even for kids!) at the push of a button and has a flip-up lock to keep it shut. The lid screws on securely, won't leak when the spout is fully closed, and has a built-in carrying loop for traveling convenience, making this lightweight drinking bottle perfect for everyday adventures.
