As the name implies, Giro's Merino Seasonal Wool Socks were constructed using a blend of smooth "seasonal weight" wool. The merino wool in the makeup helps the socks breathe, wick moisture, and resist the buildup of odors, while also providing medium-weight insulation for cool-weather conditions. Every pair of the Merino Seasonals are made in Italy, and the 6in cuffs provide plenty of coverage for both road and mountain riding.
