Buoyant Adjustable Eyewear Retainer

32.5 cm (12.8 inch) retainer combining high-buoyancy foam core with tightly woven polyester sheath. Total weight under 15 g. Unisex, non-gendered sizing with infinite adjustability via sliding loop. Skin-safe surface suitable for sensitive or sun-exposed skin. Prevents eyewear submersion in any water environment — pools, oceans, lakes, rivers — and supports rapid reacquisition post-drop. Compatible with plastic, metal and acetate sunglass frames, plus all common swim goggle strap types. Used daily by swimming clubs, marine guides, surf schools and holiday rental operators — where equipment loss directly impacts operational cost, guest satisfaction and environmental responsibility (reducing plastic waste from discarded eyewear).
