Most swappable-lens goggles use complex, gloveproof side levers or push buttons to pop lenses in and out, making changing your goggles to match conditions an ­irritating process. Not so with the Anon M1, which simply holds the lens to the frame with six magnets and three quick-release tabs. Just press the tabs, pull off the lens, and replace – you don't even need to remove the goggles from your face. [$220;]
