Humans have dated the first wool garments back to ~3500 BC. It’s an incredibly useful fabric that retains heat, insulates, and readily absorbs moisture.

Merino wool comes from a breed of sheep known as Merinos. It is finer and softer than the wool from other breeds of sheep. This results in a fabric that harnesses the benefits of traditional wool without the itchy feeling.

Merino wool socks are great all-season socks that are especially suitable for outdoor weather. They wick away moisture and keep your feet cool in the summer, yet also insulate and keep your feet warm in the winter. Merino wool is a high quality fabric, and accordingly costs more to produce than your typical cotton.

In this list, only light or ultralight cushion options are shown as they will be functional all year long. If you are looking for extra comfort or additional insulation against cold weather: cushion, full cushion, and extra cushion options are also available.
