Although not an original 930 tartan pattern, the Magnus is a tribute to Magnus Walker's own plaid designs. Who's he? If you need to ask you're probably not a petrolhead. Magnus Walker is a fashion designer, style icon, automobile enthusiast—and owner of one of the world's most astonishing collections of Porsches, particularly 930 911 Turbos. 80% Combed Cotton, 17% Polyamide, 3% Elastane. We use seamless knitting to create a sock with no stitches. Wash inside out (40ºC/100ºF max). Do not tumble dry, iron, bleach or dry clean.
