Leak-proof with a unique air valve, safe even when tipped over. Note: 'leak-proof' does not apply in cases of misuse, air valve damage, or aging. This product is not completely sealed. If left on its side for several minutes with the cover open or shaken, the liquid inside may leak. The straw inside the bottle always comes to the front for easy drinking until the last drop. The screw cap design allows for easy opening and closing. Made from lightweight and durable Tritan, which is transparent for easy viewing of contents. Designed for small hands to grip easily. The handle can be removed for compact carrying.
