As summer is here and the heat is rising many of us battle with staying cool while out on the course. Zoot Sports has something that may help us stay a tad bit cooler while at the same time protecting our skin from the harmful rays of the sun. The Zoot IceFil Arm Coolers beats the heat by using a combination of Xylitol and thermal radiation nano technology to reduce skin temps up to 5.4F/3C. This may not sound much but it is huge when energy is consumed trying to battle the heat.
