Keep drinks cool for longer with The First Years Insulated Straw Cup! The silicone straw spout helps keep liquid away from teeth and is textured to encourage your child to sip from the top portion of the straw. Great for families on the go, the silicone valve in this straw sippy cup helps prevent leaks so that drinks stay inside and off of your little traveler. Kids will drop things, but the sippy cup lid has a DropGuard™ bumper that helps prevent breakage. When the cup is empty, the dishwasher safe design makes keeping it clean simple.
