Christmas socks are sold both as single pairs and in multi-pair sets; for example, some listings show single-pair packaging while others offer multi-pair packs such as a 15-pair Christmas sock set.
Common materials include cotton and cotton blends, polyester and polyester blends, and blends that incorporate wool, polyamide (nylon), and stretch fibers like spandex/elastane.
