Fox River Trail Pack
Here's what other sites are saying:
the Trail Pack sock is made of super soft merino wool and acrylic that combine to provide great moisture management. It has a fully cushioned foot with flat knit side channels for air flow and a form fit. Elastic arch panels promote circulation and hold sock in place. This sock also has smooth linear looped toe seams for no irritation at the toes.
The soft warmth of Merino wool blends with the smooth, lightweight durability of acrylic in this breathable, moisure managing sock.
