Picked up a 'swamp cooler' vest from the HD dealer today. 98201-13VM. Soaked it as recommended and went for a ride. Temp 97 deg and humidity Florida high - prolly worst case for evaporation cooling, but vest worked great. I can't believe I've used $high electric cloths for heat but never had one of these evaporative cooling vests before. Cost < $50. :clap:
