This continuous evaporation process helps to keep you cool as your body heat increases, and warm when temperatures begin to drop. UPF+50 fabrication combined with Quik-Wic technology is the highest priority for baselayers and next-to-skin surfaces making the Heatshield vest the ultimate cycling baselayer.
