The Smith I/O MAG is a fantastic medium-sized goggle system that comes with two easily interchangeable lenses: one for sunny conditions and one for flatter light. The magnetic change system is quick, easy and incredibly secure. And, if you are looking for an oversized goggle, there's the I/O MAG XL. For smaller faces, there is the I/O MAG S.

No single lens is ideal for both stormy/flat light and bluebird days, but with the Smith I/O mag you don't have to choose: the Chromapop Rose Flash lens that comes included as the low-light lens with most I/O MAG goggles is easily the best low-light lens I have ever used, perfect for most Winter days in the Northeast. The sunny day lenses are ideal for bluebird days in the High Alpine West and Spring skiing in the East.

The I/O MAG has excellent anti-fog properties. I have never experienced fogging under normal conditions. Any goggle that gets soaked in the rain, or fills up inside with snow can fog up, but the removable lenses make it much easier to dry out both the lens and the goggle frame before day 2 of a ski trip where day 1 is a monsoon.

In short, The Smith I/O MAG goggle is a fantastic choice for any skier who wants the ability to change lenses with quality optics on the fly (or at least on the lift) for a mix of low-light and bright conditions.
