The Noggle-Making The Backseat Cool Again-Quick & Easy to Use Car Travel Accessories for a Comfy Ride Summer or Winter-Air Vent Extender Hose Directs Cool or Warm Air to Your Kids - 6ft, Lt. Blast

Best thing I've bought for the Dubai heat. Little one is much happier sitting in her rear facing seat with this, before she would always get hot sweaty and cranky.

I put it from jeep to a rtt this Is a video of my test run works best with 2

My son-in-law tried to install this and had to use duct tape to get this to even barely work. It's long enough, but only works if the AC is on full blast. Way too pricey.

Great idea, I think a larger diameter would work better. I also think that taking a measurement is very important because we went with the largest one and by the time the air gets to the third row it’s very little air and it’s not as cold as one would imagine or as it does come out for the driver and passenger we install this in our Honda pilot 2016 model for the third row we ended up purchasing fans that plug into the cars rear outlet they work very well we now use this to get some air to our newborn car seat which is rearfacing.

This item is so nice for kids in the backseat that don’t get air flow. It will be perfect for summer time! At first it will push out the hot air. But once it has cold air pushing through it works great!

Not enough air flow
