Increased UV protection, glare reduction and optical clarity
The Smith I/O goggles have been newly redesigned with a slimmer outrigger on the sides to provide a wider peripheral view. Smith also increased the size of the tabs at the top of the frame to make swapping lenses easier while wearing gloves. The spherical Carbonic-X TLT lens mirrors the natural shape of your eye to minimize distortion, improving vision quality while decreasing eye fatigue.

To prevent moisture from cramping your time on the hill, Smith added their 5X Anti-Fog inner lens. When Smith created the I/O, they essentially invented a category. As the original interchangeable goggle, the I/O is the standard by which all other goggles are measured.

Frame Features

Articulating Outrigger Positioning System - A key element in goggle/helmet compatibility. Engineered to adjust to a full range of face shapes and sizes, the Articulating Outrigger Positioning System evenly transfers pressure across brown and nose to ensure a complete seal against the face. When used with a helmet, the outrigger articulates allowing the goggle frame to sink into the helmet face port, providing a comfortable and consistent fit every time.

DriWix 3-Layer Face Foam - Increased density in base layer foam reduces hot spots helping form a tighter seal on the face. Mid-layer foam provides a plush comfortable layer, perfectly sealing on the face and absorbing sweat and moisture. Fleece lining is soft against the skin for long-lasting comfort.

QuickFit Strap Adjustment System with Clip Buckle - Provides easy and convenient adjustment with the addition of a clip buckle to prevent the strap from slipping out of fit.

Responsive Fit Frame Design - The Responsive Fit design allows the frame to adjust and flex to the contours of your face.

Every face is different. By reducing material and creating a flexible architecture, Smith's frames act like a suspension system that micro-adjusts to your unique facial structure, ensuring a precise, comfortable fit.

Ultra-Wide, Silicone Backed Strap - High quality, durable, double-woven strap features a silicone bead for superior helmet compatibility. Distributes pressure evenly around the head for an excellent fit, adjustability and comfort.

Lens Features

Spherical Carbonic-X Lens - Smith has set the standard in lens performance. Each lens is individually molded to offer optimum scratch and impact resistance, increased visual acuity, and enhanced contrast sensitivity. The inner lens is impregnated with Smith's Anti-Fog lens treatments for increased anti-fog performance. The Carbonic-X lens meets Class 1 optical standards as well as ANSI Z80.3 standards.

100% UVA/B/C Protection - All Smith lenses provide 100% protection from harmful UVA/B/C rays.

5x Anti-Fog - Building upon the hydrophilic, micro-etched surface area principles of Smith's Fog-X lenses, the 5X Anti-Fog inner lens has been engineered to provide more than five times the absorptive properties of anything on the market. Initial testing showed standard anti-fog lenses fogging between 30-50 seconds. Smith's proprietary, 5X Anti-Fog treatment withstood fogging for more than 120 seconds in controlled lab tests.

Porex Filter Technology - Changes in elevation bring changes in atmospheric pressure. These forces have the potential to diminish the optics of thermal lens systems. Smith's patented Porex filter solves this issue by allowing the air pressure within the sealed lens chamber to equalize with the atmosphere outside, ensuring class 1 optical standards.

Tapered Lens Technology (TLT) - When light passes through a medium it refracts, or changes course. If left uncorrected this refraction can cause visual distortion and eye fatigue. Smith's Tapered Lens Technology straightens out the incoming light rays by progressively tapering the lens from the optical center toward the peripheral view. What this means for you is that you see with 100% accuracy and maximum comfort.

Quick Release Lens

I/O - Flip the top switches, pop out the lens and replace it with a new one.

Bonus Lens VLT

Most bonus lenses have a higher Variable Light Transmission percentage, so they're suited better for low light situations. We supply you with the specific VLT rating and the riding conditions that the bonus lens excels in. We care about tech.

Smith Red Sensor Mirror Lens - VLT Rating: 55%

Excels In: Overcast

Excels In

VLT stands for Variable Light Transmittance, which is the percentage of light that is allowed to penetrate the lens, for brighter conditions you'll want a lower VLT rating and with darker conditions you'll want a higher VLT rating.

Sunny - VLT between 0% and 18%

Smith I/O Goggles - black/red sol-x lens + blue sensor lens
Great fit with Vantage small helmet. Great size, not too big for smaller faces. Lens options are great for sunny and cloudy. Used the red mirror on bluebird day and it was great. Normally use the sensor lens for low light cloudy days. Great visibility and depth perception in both situations.

Smith I/O Goggles - bone prospector/blue sensor lens + red sol-x lens
These goggles fit and work great. I haven't hiked in them yet, so I don't know about fogging, but have heard they're great. I've already used both lenses in high/low light situations and it's really easy to swap them.

Smith I/O Goggles - black/red sol-x lens + blue sensor lens
Had an old pair of Smith goggles for the last 10 years that were still going strong but finally decided to upgrade to a dual lens pair that could cover both ends of the weather spectrum. These bad boys worked awesome and allowed me to quickly and easily switch out the lenses when bluebird became overcast over the course of the week. Great field of vision and never had any fogging issues for the first time in my life. Well done Mr. Smith!
