In lunchtime or afternoon heat, technical running clothing helps keep you cool, dry and comfortable by letting your body breathe and by moving sweat away from the skin. Ronhill’s Vapourlite fabric, for example, has a light, knitted construction which wicks away moisture and dries quickly to combat excess heat and sweat.
Other nifty warm weather fabrics to consider are Nike Dri-FIT, which has mesh ventilation in the areas where you sweat the most, ASICS Motion Dry technology and GORE’s stretchy Microfiber, which keeps the body at a temperature where it can physically perform at its best (GORE claims that this is around 37°C).
There is also adidas’s ingenious SubZero yarn, which contains titanium and aluminium-silver microdot beads to cool you by conducting heat away from the body. The beads are located where you sweat the most: on the back, neck and the back of the arms.
Finally, technical running socks help reduce the risk of blisters by keeping your feet drier and cooler (read up on the benefits of technical running socks).
