Rupert - Grey and black buffalo knit merino knee-high socks for men. Please note - the way the Rupert sock is knitted means that little threads will occasionally pop their heads through at the colour change. These can be safely trimmed off without damaging the sock. We recommend washing these inside out. New Zealand Made, sizes knitted into every pair so no confusion over whose are whose! 70% Merino Wool, 25% Nylon + 5% Elastane Colours may vary slightly to photo depending on the batch.
