These are used socks with ample pilling, but they have no holes or thin spots and are structurally sound. Merino wool and smart wool socks are great for being quick dry, light weight, temperature regulating, antibiotic, and odor resistant. They’re great for travel since you can get multiple wears between washing. Unfortunately, I developed a wool allergy so am slowly selling all my pieces of marino wool and cashmere. Check my closet and bundle for a deal!
