Milosport Butterknife PRO Polarized Acetate Sunglasses
Park-Lap Precision. Heavyweight Street Style Meets Top-Tier Optic Sharpness.
The Milosport Butterknife PRO Sunglasses represent the absolute crown jewel of our premium acetate lineup, custom-engineered for riders who want high-end street craftsmanship without sacrificing technical muscle. Named after the buttery, smooth-flexing park boards that slice through spring slush, the Butterknife PRO swaps out standard injection-molded plastics for the substantial feel and rich luster of hand-cut Italian acetate. Backed by an upgraded, high-contrast polarized lens package, these shades deliver a bold, blocky layout that stands up to the absolute heaviest glare on the mountain or the concrete.
Milosport Shop Take
"Yo, the Milo crew is fully backing the new Butterknife PRO. We took our absolute favorite casual block profile and completely upgraded it with team-level tech. The second you pick these up, you immediately feel the weight and quality difference of that premium hand-cut acetate. They look ultra-premium whether you're traveling, hitting tailgates down in SLC, or lapping the park during those heavy spring slush sessions up at Brighton. Plus, we loaded the PRO edition with our sharpest polarization to completely delete blinding snow glare while keeping your style on point."
Look, if you appreciate fine craftsmanship but still live a rugged mountain lifestyle, these are your daily drivers. Hand-finished cellulose acetate gives these frames a deep color depth that cheap plastics can never replicate. Inside the temple arms, we embedded a structural stainless steel wire core, which means you can easily heat-mold and customize the fit perfectly to your face shape so they never slip when you're moving fast. They cut down on eye strain instantly, meaning no more headaches after a long day under the high-altitude sun.
