Improved Sunglasses Strap Holder: Unlike other silicone floating sunglasses strap holders that are inelastic, rigid, and difficult to attach, our sunglasses strap features a silicone loop design with high elasticity, making it easy to attach and providing a secure grip. It prevents your sunglasses from slipping or falling off. Adjustable and Comfortable to Wear: You can adjust the length of the sunglasses strap (ranging from 0 to 16 inches) using the adjustment buckle. This allows you to wear them loose and keep the strap around your neck, snug against your face, or anywhere in between. Easily access your sunglasses and wear them however you prefer for maximum flexibility. Durable Material: The sunglasses strap is made of high-quality neoprene and dense foam, making it lightweight, durable, and quick-drying. Our sunglasses strap provides sufficient buoyancy to prevent your sunglasses from sinking in the ocean, lake, or pool. This glasses strap is made of soft, highly elastic silicone. A variety of colors are available for you to choose from. Fits most frames: Our glasses straps are designed to be your go-to glasses holder all day long, no matter the size of your adventure. The hole for the sunglasses holder has a diameter of 4.5 mm (0.18 inches), accommodating temple sizes from 5 to 12 mm (0.2 to 0.5 inches). Perfect for sports activities like kayaking, boating, fishing, and swimming, as well as securing your sunglasses on day trips or family vacations.
