In recognition of BMW Motorrad's 90 years of motorcycling excellence, Ruby has released a series of high-end headgear, the Ruby Munich 90 Helmet Collection ($980-$1,450). While there are certainly less expensive ways to keep your brains intact, there are relatively few that look like these helmets. With design cues taken from the bikes that inspired them — including the classic red and blue stripes on a white field — these helmets come in three variations and a range of colorways. Choose the Belvedere, with its large front visor, the Pavillon, with its exposed face, or the partially enclosed Castel.
