Each pair of Organic Daily Mini Crew Socks is ideal for daily use regardless of season and can be matched with a variety of styles. It is knitted with a low-gauge knitting machine that is hard to find today with fuzz-resistant thick organic cotton yarn called ‘compact yarn.’ The comfortable brushed sole and gentle fit give less stress. With the not-too-long length, this pair can be worn in many seasons. The chic color options make this item a perfect gift idea. 54% Linen, 8% Nylon, 5% Polyester, 1% Polyurethane Size M = Size 8 to 10 Size L = Size 10 to 12 Avoid tumble drying, as it may cause shrinkage.
