The Darn Tough Style 6085 Spey Fly is a fine-gauge merino wool crew sock with a thin layer of cushion along the base of the foot. It’s built as a Lifestyle-line sock, meaning lighter overall than the hiking versions while using the same True Seamless toe construction to prevent the seam irritation that happens in cheaper socks.
Crew height sits mid-calf to stay up through the day, and the 51% nylon / 47% merino wool / 2% Lycra blend keeps the sock breathable, quick-drying, and temperature-regulating across seasons. Built for casual wear, office days, travel, and anyone who wants the durability of a Darn Tough without the bulk of a boot sock.
Every pair of Spey Fly socks is knit in Vermont with yarns sourced from America and around the globe. Darn Tough stands behind every sock with their unconditional lifetime guarantee.
