Hey, so I was going to take a 200 mile trip with my g/f to North Carolina today, I don't have air conditioning and it was 85 degrees out side and I did not want to sweat the whole way. I got 2 of these lumbar support things for the air to the back (see picture) at CVS, I was planning on getting back from the trip and returning them...Nope, these things are freaking awesome! instead of rolling the windows down all the way I rolled them down about 25% and stayed really cool, it was great. I got 2 for $11, I HIGHLY recommend these if you don't have a/c.
