Cabela's XPG Lightweight Hiking Socks bring the softness of merino wool and the structure-giving support of Lycra® to your outdoor adventures. We used the highest-grade merino wool because it creates a breathable, itch-free, moisture-wicking fabric that acts as a natural temperature regulator. It keeps your feet from heating up during the summer and it helps generate warmth when it is cold. The stretchable Lycra is knit throughout to provide durability, shape retention and form-fitting comfort. Built-in arch and ankle supports provide relief from fatigue. High-impact zones have been reinforced and lightly padded to absorb ground shock. The reciprocated heel and toe pockets and seamless toe construction team up to hold the socks in place and reduce friction. 55% merino wool, 43% nylon, 2% Lycra spandex. Made in USA. Ht: 5". Men's sizes: M(6-8), L(9-12), XL(13-15). Colors: Red, Yellow.
