What Our Gearhead(R) Experts Are Saying:"I swapped lenses at the top of a run when clouds rolled in, and the magnetic system took maybe five seconds without removing my helmet. The wide field of view made spotting other riders in a crowded terrain park way easier than I expected."Conditions on the mountain shift fast, and the 4D MAG S Goggles from Smith are built to shift right along with them. We drop into a run under bright sun, feel the ChromaPop lens sharpen every contour of the terrain, then swap to the low light lens in seconds when the clouds roll in. Built for a smaller face, they stay locked in through every lap without ever needing a second thought. The MAG lens change system relies on magnets instead of fiddly clips, making mid mountain swaps genuinely quick. BirdsEye Vision widens the periphery so other riders stay visible at the edges, while three layer DriWix face foam wicks moisture to keep fog from ever settling in. An ultra wide, silicone backed strap holds everything in place, and AirEvac venting pairs with a Smith helmet for a fully integrated, fog free setup all day long.
