Adjustable silicone strap set

This two-pack supplies black silicone cords that slide to fit any head size between 9.06 and 13.78 inches. The material resists scratches and stays supple during extended wear. Each strap loops onto standard spectacle temples without tools.

For active eyeglass wearers

Hikers, cyclists and runners who need glasses to stay put during motion will find the adjustable grip reliable. Spectacle users who prefer a rigid retainer or a metal chain should consider a different style.

Length range 9.06 to 13.78 inches

The single measurement that decides fit is the adjustable span of 9.06 to 13.78 inches; if your head circumference falls outside this window the straps cannot secure the frames.

Questions about this item

How much length can I actually add or remove from the strap once it is on my glasses?

The silicone cord slides between 9.06 inches and 13.78 inches so you can tighten it for sport or loosen it for casual wear.

What connection does the strap use to grip the temple tips and will it fit standard frames?

Each end forms a flexible silicone loop that stretches over typical temple tips; no special hinge or screw mount is required.

What clearance do I need behind my head for the strap to sit without catching on a collar or helmet strap?

At its shortest setting the band measures 9.06 inches end to end, so it rests close to the neck and clears most collars and helmet retention systems.
