A Noggle is a child comfort system that controls the air temperature in a car's backseat: How it works: • The Noggle hooks onto a car's vents and sends air to the backseat. • It can be used to: • Keep children cool and comfortable in the summer • Keep children warm and comfortable in the winter • Keep pets comfortable We loved this when we used it for my child while they were rear facing (car was a standard sedan for reference). I have all the accessories, but you can see one of the zip ties was used (I actually think the shaping made it easier to get back into the vent the second time around). Features: • The Noggle is: • CPSIA tested and approved • Quick and easy to install • Lightweight and flexible • Includes rectangular and circular adapters to fit most car vents • Comes with a matching loop to attach to the headrest, car seat, or backseat handle • Features a quick disconnect system
