Socks and Underwear: A Simple Materials Guide

Socks and underwear are worn all day, so the material makes a real difference to comfort. Here is how the common options compare.

Cotton

Soft, breathable and widely available. It absorbs moisture and dries slowly, so it suits office days more than workouts.

Bamboo and modal

These are very soft and drape smoothly. They feel cool against the skin and suit warm climates.

Merino wool

Merino regulates temperature and resists odor, which makes it good for socks in both cold and warm weather. It costs more but lasts well when washed gently.

Nylon and polyester blends

These dry quickly and keep their shape. Blends with a little elastane add stretch for a secure fit.

Buying tips

Buy in multipacks to save money, and replace pairs when the elastic loosens or the fabric thins. Pick seamless or flat-seam styles if you are prone to rubbing.
