The I/O 7 upgrade centers around the single-pivot quick release system that enables probably the single easiest lens swap of any pair of ski goggles we tested. The I/O was the goggle that brought interchangeability to the market in a real and meaningful way. While most goggles at the high end of the spectrum have always had swappable lenses, Smith made it easy enough to have a one goggle quiver with the I/O. In addition, Smith sells the I/O with two lenses included: a low-light option for storm riding, and bright-day lens for when it goes bluebird. But interchangeability is only part of the story.
Quality optics are defined by the clarity of your vision as any lens in front of your eye causes distortion – the lesser the distortion, the better the clarity of vision. Smith’s spherical lens features curvature along both the longitudinal and vertical axis, which offers exceptional vision with minimal distortion. Additionally, a Porex filter allows the pressure between the two sealed lenses to acclimatize to changes in elevation, further reducing distortions. Smith goggles come in a vast array of lens choices, with differing light transmission rates, hues, polarization and technologies like Chromapop that filters two specific wavelengths of light, which enables the wearer to see with greater definition with improved detail and color clarity.
Although the lens is likely the most critical part of the goggle, there are other important elements to consider. Fit takes center stage on that front. Smith offers a host of features to ensure a proper fit, including outriggers for different helmet sizes, a silicone backed strap for stability, 3-layer face foam for comfort and an adjustable strap with a secure clip. Bottom line is the I/O 7 Chromapop is the culmination of all of Smith Optics’ expertise. It combines all of the top-tier proprietary lens technologies and design knowledge in a package that enables swift and easy lens changes.
Pros: Solid fit and premium optics
Cons: The medium fit may be too large for smaller faces, who will want to opt for the I/OS instead
Tester Comment: “Comfortable for medium to large faces, the I/O 7 performs in any condition. The Sensor Mirror low-light lens is my go-to for storm days.”
