Smith is one of the largest outdoor sports brands in North America, with a number of highly recognizable ski helmets and goggles that are among the best in the market, creating several industry firsts. The first pair of ski goggles with sealed thermal lenses and breathable exhaust foam was made, and on this basis, the first pair of double-lens ski goggles was launched to solve the problem of atomization. Today, Smith's designs are still the industry standard.
 
In December 1978, Amy, the daughter of U.S. President Jimmy Carter, was photographed by the media wearing Smith's ski goggles while on vacation, making Smith's ski goggles famous. In 2012, Smith made protective eyewear for surfers, snowboarders and military special forces, with annual revenues of more than $100 million. At present, Smith's core business is still ski goggles, followed by sunglasses, ski helmets and motocross goggles.
 
In order to increase contrast and enhance clarity while skiing, high-end ski goggle manufacturers have their own optical technologies, such as Oakley's Prizm technology, Smith's Chromapop technology, and Dragon's Lumalens technology. Smith's Chromapop technology is an important weight in its ability to compete with Oakley, helping the eye see more detail and color by filtering out specific wavelengths of light that cause color confusion. At the same time, the hydrophobic lens coating protects against moisture, grease and dirt, and even if fingerprints are attached to the mirror, it can be wiped instantly, keeping the lens clear and clean.
 
Smith's I/O line is well-known in the industry and is one of the most imitated ski goggles. The new I/O mag ChromaPop retains the classic I/O series look and has an improved lens replacement mechanism. In addition to the double locking system, the frame is also equipped with 8 magnetic strips, making it easier and faster to exchange lenses. However, the inner and outer rim lenses are a bit smaller than the Oakley Flight Deck series, so the top-down and side-to-side fields of view are also slightly narrower. I/O mag ChromaPop with interchangeable lens, priced at 1920 yuan.
 
On top of that, Smith's Squad series was a smash hit when it was launched, and the new Squad XL is a larger model with a line of sight that rivals the Oakley Flight Deck series. And it has two ChromaPop lenses to adapt to changing light conditions, and the price is competitive with the single-piece Oakley Flight Deck. However, Squad XL has restrictions on face shape due to its ultra-high size and flat contour, and it may be a little strange to wear a medium-sized face shape, priced at about 1040 yuan.
 
For beginners who only use ski goggles occasionally, Smith's Project series is the best fit for the budget, with dual lenses that reduce fogging, keep them clear most of the time, and are helmet-compatible. The only bad thing is that the Project Goggle series is lined with a single layer of foam, if the follow-up skiing is frequent, and the use time is increased, the single-layer foam will not only be less comfortable than the previous series, but also wear out faster, the price of this model is about 480 yuan.
