Rototo Rain Drop Crew Socks Dark Brown / IvoryThis unique pattern adopted by the East German Army and the Czech Army is now known as the Raindrop Camo because it looks like falling rain. By adding a modern twist to the design, the classic pattern is beautifully knitted in a pair of socks with a low gauge knitting machine. Yet with chunky texture, the item naturally blends in not just casual outfits but also sophisticated looks.
