Why we use merino wool in our socks:

Merino wool is a type of wool that comes from a merino sheep. It is the finest wool on the market, making the fabric soft and itch-free. It is also breathable and temperature-regulating, so your feet are not too hot or cold. Merino is one of the best fibres for wicking moisture as it can absorb up to 30% of its weight in moisture and moves it from your skin to the outside of the fabric, where it evaporates. Because it stays dry, odour-causing bacteria cannot grow, making it a naturally antimicrobial fibre.
