Just like the previous model, each item is knitted with organic cotton yarn by an old-style low-gauge knitting machine that only a few craftsmen can operate. The eye-catching coloration is inspired by outdoor wear made in the 1980s and 1990s. The fabric is thick and durable, but also has excellent breathability because of the chunky stitches. Each pair goes well not just with sneakers but also with sandals. MATERIAL 93% COTTON、5% NYLON、2% POLYURETHANE COUNTRY OF ORIGIN Japan * Avoid tumble drying, as it may cause shrinkage. * Due to the characteristics of chunky, low-gauge socks, this product may have loose yarns or elastic thread around the cuff after repeated use and washing, but it does not necessarily mean that the fabric is fraying. Do not pull loose yarns, simply cut them off from the roots with scissors.
