You may not know this but it can get temperature extremes here in Australia. And I like riding my motor bike as often as possible, with the least amount of clothing as possible (no I don't ride in my birthday suit before you ask!).

The temperature range can go from -10 to 40 deg C in one trip, so I think having this jacket take care of my comfort would be great!

I have proven the concept by having the peltier cool or heat water in some tubing on the floor of my shed. Not pretty but it works.

Next I need to replace my homemade water tank with a proper CPU copper water block.
