Chup - Dafad Wool Crew Sock - Charcoal. Chup is one we keep coming back to every season. They've been in the lineup for years now and we're more impressed every time. They hold up to washing and drying (though they don't recommend it). That's even more impressive to us. The combed cotton is Made in Japan and carries no impurities. It's also stronger and fluffier than your everyday cotton. The patterns are what sell you upfront, but the quality is what keeps you coming back for life. DAFAD - Wales in England is surrounded by magnificent nature with deep shades of green and bare rocks. Flocks of sheep shine golden under the sun, expressing the beauty of life. “DAFAD” means “Sheep” in Welsh.
