SNOWFIELD by SWANS SF (Photochromic Lens Model) | Old-School Sunglasses You Won't Need to Change All Day

From the dim hours of morning to the strong midday sun. A photochromic lens model that adapts to changing weather conditions.

With a classic aesthetic and all the features needed for modern rides, SNOWFIELD by SWANS SF combines an old-school design reminiscent of 80s and 90s sports eyewear with the high quality unique to the Japanese brand SWANS.

Its main feature is the photochromic lens, which changes density depending on the amount of UV light. It remains nearly clear during dim morning and evening hours or on cloudy days, and darkens to smoke when the sun is strong, eliminating the need to switch sunglasses for different scenes.

The wide lens and goggle-like frame shape provide a wide field of vision and excellent wind protection. It reduces the intrusion of wind and dust during rides, supporting a comfortable view.

Weighing only 28g, it's comfortable for extended wear. It's a versatile eyewear perfect for cycling, running, hiking, and everyday use.

This is one of the models where I personally feel the convenience of photochromic lenses the most.

During early morning commutes or at the start of a ride, it stays nearly clear, ensuring visibility, and then naturally darkens as the sun gets stronger, eliminating the hassle of switching sunglasses. You can really feel the comfort, especially on long rides and tours.

Despite its classic appearance, its field of vision and wind protection are excellent. It's recommended for those who dislike overly sporty sunglasses or are looking for a pair that can easily be matched with everyday wear.
