This is the homemade version I'd started collecting parts for. Skip to the 2 minute mark to see internals. There's almost no way for it not to push tons of cold air. For awhile at least...
AIR COOLER fits passenger side of AD bench seat Decided to go a different route when a friend loaned me his
HyperKewl It's amazing. Simply soak in water, gently wring out, and zIp up. Stays cold for hours. Took Shelley for a drive in the afternoon heat (95F) and was very comfortable. Got home hung it up darn thing was still
cold at bedtime 10 hours later.
Not just for desert climes...have poured water down my shirt many times riding a motorcycle in the humid southeast so I know evaporative cooling works to some extent there too.
A cooling vest may not be the solution for everyone, but it's alot more convenient than a 30 lb ice chest on the seat beside you.
For the price ($36 on Amazon) I don't think I can beat it.
