Bajío’s Silicone Keepers are total keepers for so many reasons! Durable, lightweight, low profile and waterproof, these flexible 100% Silicone Keepers are designed to be worn full length or they can be adjusted for maximum comfort and versatility. In fact, the 16-inch length is so flexible it stretches to 32 inches. These keepers also offer non-conductive properties which means no neck burns on hot, sunny days. The universal rubber ends fit most framed glasses. And these keepers are available in four different colors: Pink, Gray, Black and Light Blue.
