Mike Newberrywrote a review of Smith I/O X Interchangeable Goggle on February 27, 2017
Familiarity: I've used it several times
No one evers 'needs' anything gear-wise, just wants new gear...same here. My 'old' googles were fine, I just wanted a new pair...these, obviously, rock. Extra, low-light, lens included and the main bright light lens is great....LOTS of visibility. Lens interchangeability is a snap and could be done on the fly if need be....bottom line, go get a pair.
