Any suggestions on waterproof + airflow seat covers??

This looks like a decent solution, but I'm worried about the black beads (especially the ceramic "ultimate" version) getting crazy hot in the Texas sun when parked. Do you know which you have? Also, the quick disconnect straps are extra, otherwise it looks like you have to remove the seat to install/remove them.

I use the wooden beads... They don't get hot in the sun...(not sure about ceramic) I also use the quick disconnects.. easy on and easy off... Honestly I only take it off to clean the seat or if the temp is below 50 degrees.. One time, I left my house when the temp was 45 degrees made it about a mile down the road.. I had to stop and take the beads off the seat because it was way too cold on my bottom.. That was enough proof to me that they allowed airflow...LOL
