Pros Inexpensive, comfortable, fits great with helmetsHigh quality optics, easy lens changes, field of visionMagnetic lenses, magnetic facemask, 2 lenses included, great optics, best performance for large facesMagnetic lenses, 2 lenses included, great opticsExcellent optics, durable, easy to change lenses
Cons One lens included, relatively basicPriceExpensive, larger fit not for everyoneExpensive, medium fitExpensive, visible frame around nose, drafty
Bottom Line A relatively simple but highly functional and comfortable goggle for those on a budget.The best optics, lens changeability, style, and durability in a medium-fit goggle.The M4 knocks our socks off with great optics, user-friendly features, and an excellent fit for large faces.With a new magnetic lens system, this is the newest member of Smith's popular I/O line of goggles.An impressive goggle with excellent optics and solid all-around performance.
