These goggles are so incredibly easy to swap around. Because this NZ winter switches from cloudy to sunny constantly I have found that my interchangeable lenses makes life so much easier. A simple little twist and the magnets do their magic. No need to fiddle around with different lenses and spending time on trying to change them, these lenses can be swapped within a click. They also come with a magnetic face mask, a mask that will NEVER fall down. Not only are they practical but also incredibly stylish.
