Relief for An Hour or so
The vest works well for about an hour. Just got to use for the first time as we traveled through Death Valley, Las Vegas (where it was 106), Grand Canyon and the Monument Valley. Temps were in the 90's for the most part. Did not experience any 'sliminess' as other reviewers have experienced. One of crew is towing a trailer with a cooler on the front. We soaked our vests in the ice water and we actually were extremely cool (almost cold) for the first 20-30 minutes even with temps near 100. After about 45 minutes, effectiveness was much less but still better than without. If you can stop every hour and recharge, it will keep you cool for your ride. I thought about buying a 2nd vest and keeping one in the ice water while wearing the other and alternating them. The price is low enough to put out for another vest.
