Neoprene Chums Retainers are a favorite of river rats, beach bums and anyone that spends time on the water. This limited-edition eyeglass retainer features original artwork by Idaho guide Heidi Messner. Proceeds benefit the Redside Foundation, supporting the health and strength of the professional guiding community in Idaho and Montana. The industry standard for neoprene retainers Chums are lightweight, quick-dry and easily adjustable. Lock-stitched ends slip over most size eyewear frames. For a tighter fit, slide the retainer further down your frames. Will float frames weighing up to 15 grams. NRS is proud to partner with Chums on a limited edition range of custom products to support the Redside Foundation and the guiding community.
