I don`t have that brand but I do have a cooling vest. It works, period. Here it gets well above 100*F. Some days are 110*F and up. I just got my vest early last summer after a ride where we were at 70*F that morning, and a ride to the coast (2hrs). The coast was in the high 40`s (did not dress for this). Then had lunch and headed home. Coming back on HWY 166 it got up to 105*F. We stop to rest and buy drinks, my riding buddy pulls out this cooling vest from a ziploc bag and says it is hot! OH, no $hit! The ziploc bag was filled with ice before he left home. It was melted now, but the vest was cool. I burned up, and he was cool.
Just soak the vest in water let the excess water drip off and put the vest on under your jacket and go. It will make a marked difference in your riding comfort.
Hey dude, linky no worky.
