The Stanfield's Graphene Heatfx® Socks - 2 Pack were created for outdoor and work purposes, but its temperature-regulating yarn blend of graphene and Merino wool also makes it ideal for everyday wear. Derived from carbon, graphene is a natural mineral that is lightweight, flexible, and technologically advanced in providing exceptional warmth. The fibers absorb heat energy from the body and emit it back to keep you warm where it's needed. Additionally, this sock is inherently anti-odor and has excellent wicking properties, ensuring its technical capabilities will last. Despite being a mid-weight garment, it has a soft, airy feel. The crew-length socks offer 360º arch support and a full-body cushion for comfort and protection against abrasions. The 2-pack set includes one pair each of navy and charcoal. Care instructions recommend turning the socks inside out before machine washing on a cold cycle and avoiding bleach and fabric softeners. Tumble dry on low heat and do not iron, dry clean
