Bests & Worsts Reviews from Amazon

There's a reason they advise to keep out of the sun or high-heat places like your car - the 'sweat' you see after a workout is simply the same gel you applied in liquid form (it turned into liquid because it melted with your own bodyheat, same as it would have if you left it in your car under the sun). Also difficult to wash off your body - will continue to melt and saturate your clothing long after your workout and shower.
