• Quick-Release Hinge The Quick-Release Hinge is a patented release mechanism for the temple hinges. The temples can be easily reinserted and clicked in to position by hand.

• Traction Grip The adidas Sport eyewear Traction Grip offers a non-slip and pressure-free stable fit. The Traction Grip provides the necessary flexibility whilst also offering complete comfort when being worn.
• Double-Snap Nose Pads To optimise the resting position on your nose, the Double-Snap Nose Bridge offers an adjustment at the width of the nose, creating a perfect fit without any pressure points. The non-slip, soft material gives a secure and comfortable feel.
