Perfect socks for hot summer weather. The yarn contains Coolmax fibers, which have an incredible "capillary effect", unlike conventional polyester. They are lighter and softer than cotton, do not absorb odors and have increased wear resistance. Simply put, Alaskan Summer socks have anti-sweat and anti-odor functions. The service life of products made from Coolmax is 3 times longer, and the drying time is 2 times less than compared to cotton products.
