This water bottle holds 16 ounces and is made of durable, BPA-free plastic. The screw-on lid has a built-in carrying loop for easy transportation, and doesn't leak when it's closed, so the bottle can be tossed into a bag for worry-free travel. When it's not being used, the comfortable silicone spout can be covered to keep it clean. The bottle is dishwasher safe and should not be microwaved.
