The new K2 Source ski goggles have the same fit, style and comfort as the K2 Source Z at a standout price. The convertible Source frame lets you optimize your goggle fit whether you wear it over or under your helmet. The two included spherical lenses can be swapped out to keep you skiing well in the storm and on the blue bird. Protect and easily stash your goggles, or just the extra lens, in the new Shot Shell Goggle Jacket.
