2026 Smith 4D MAG Goggles

The Smith 4D MAG™ sits at the top of the Smith goggle line, built for riders who want the best possible visibility when conditions get fast, technical, or flat. The standout here is Smith’s BirdsEye Vision™ lens shape, which drops the lower edge of the lens to open up your downward field of view. That extra visibility makes it easier to read terrain, spot landings, and track what is happening beneath you.

Lens changes are quick and secure thanks to Smith’s MAG™ system, using magnets to guide the lens into place and a locking mechanism to keep it there. When the weather shifts, swapping lenses takes seconds without wrestling your goggles in the cold.

About Smith Optics

Smith Optics has been pushing snow goggle design forward since 1965. The brand first made its mark with the introduction of the sealed thermal lens and breathable vent foam, a combination that helped solve the fogging issues riders had struggled with for years. That early innovation set the tone for the technology-driven approach Smith is still known for today.

Modern Smith goggles continue to build on that foundation with features like ChromaPop™ lens technology, designed to increase contrast and colour separation so terrain becomes easier to read in changing conditions. Add in systems like the MAG™ magnetic lens change platform, AirEvac™ ventilation, and helmet-integrated frame designs, and you get goggles built to perform across a full range of mountain environments.
