Cooling baselayer garments are relatively new to the market but are becoming popular as people realise the benefits of wearing them in the summer or when performing aerobic activity. The first feature of a good cooling baselayer is the quick removal of perspiration from the skins surface to the outer layer of the fabric where it can evaporate. The second feature is the low retention of heat.
Sub Zero Cool T and All Active cooling baselayers have been specifically designed to incorporate both of these features, resulting in you staying cool and dry no matter what the activity.
