Liberty Sport Piston Sunglasses Review

Since 1929, Liberty Sport eyewear company has offered comprehensive lines of sunglasses and protective glasses for most sports. The moto-centric Liberty Sport Rider Collection of four similar frame styles incorporates small, removable magnetically held pieces (called ‘cups’) that fill the normally open space where the frame and temple (ear bars) join. Thus, they help reduce wind turbulence behind the lenses by providing a more goggle-like fit for comfort and safety.

Tested and reviewed here is the Piston model, with what Liberty Sport calls Sunset Driver — a rose-amber polycarbonate lens with orange hard premium mirror coating that is scratch resistant, anti-stain and anti-smudge. This is the only tint color offered, other than clear. I was then able to have my progressive prescription added these lenses. Buyers requiring prescription lenses can get this done at just about any optical retailer.

I like the look, fit and finish  of the Liberty Sport Piston sunglasses. They provide UV400 (100-percent UVA and UVB) protection, and are ANSI Z87.1 certified, which gives me added assurance when I wear them with a helmet without a face shield. The certification process tests lenses and frames against blunt high-impact, radiation, splashes, dust, and small dust particles. They are claimed to pass all global driving standards.

The Liberty Sport Piston frames aren’t bulky, nor do they have overly large lenses. This means they fit in all my full-face helmets, including Arai, Joe Rocket, Schuberth, and Shoei. Other sunglasses with tall lenses often press the frames down hard on the bridge of my nose, but that was not the case with the Piston glasses.

The nosepad material is soft, hypoallergenic, and water-resistant thermoplastic rubber. This is extremely comfortable to wear all day, won’t slip down your nose, and allows for increased grip and durability.

The temple design holds the Liberty Sport Piston eyewear tight to my head, and the tip is adjustable to add to frame comfort. The tips also have tiny holes to accommodate the included snap-in adjustable short head strap (for use with a half-helmet). Also included with Piston package are a semi-rigid case, cleaning cloth, and eyecup pouch.

The Liberty Sport Piston sunglasses are rapidly becoming my favorite, and I get to look through rose-colored glasses giving me a perpetually optimistic perception of the world.

Liberty Sport Piston sunglasses are available in Matte Black or Matte Gunmetal (reviewed here) with clear lenses or Sunset Driver tint (reviewed here).
