Vollebak created its Equator Shirts for extreme environments and everyday use. The brand engineered them keep you cool — even when it’s ridiculously hot.
As most of the United States remains locked in the midst of a summer heat wave, many folks may be sitting in front of a fan dreaming of cooler temps.
Unfortunately, extreme heat can stop us in our tracks and keep us from doing the activities we love. Vollebak is hoping to change that with its new Equator Shirts.
Engineered according to two cooling methods, the shirts will include 10 concealed, laser-cut air vents. They’re also ultralight. Weighing only 167 g, the shirts tip the scales at less than a cup of sugar or a roll of dimes.
