Fit

The Harness have a lightweight feel and a curved fit that wraps around the face. These sunglasses provide an amazing fit regardless of the activity.  

Comfort

The lightweight plastic frame and curved shape help to make these sunglasses super comfortable.  The plastic frame did not slide even in high aerobic activities and provide a great lightweight feel.     

Lens

The Harness come with a lightweight, shatterproof polycarbonate lens that is 100% high-contrast Serilium polarized.  This allows the glasses to provide great contrast and performance under tree canopy and on the snow. The lenses were dark enough to protect my sensitive eyes on bright snow, but light enough for summer hiking and cycling.  The lenses seemed durable, but did get scratched over time.

Coverage

The Harness has a curved shape that adds to comfort and wraps well around the face providing good coverage.  This coverage helps block wind and sun from the side regardless of activity.

Features

The Harness are a straight forward pair of sunglasses with slip resistant rubber on the frame to keep them on the face.  The polarized lens is a shatterproof polycarbonate in a sporty frame with retainer holes at the ends of the arms.
