Smith’s Neoprene Retainer is a simple sunglasses strap in neoprene. It’s the add-on that keeps your shades with you when you’re wading, rowing, or leaning over the gunnel to land a fish. Smith lists it as fitting most sunglasses, so it suits a wide mix of frame styles without needing a brand-specific attachment.
This is sold as a single retainer. If you’re trying to match a very specific frame shape or temple size, this one is meant to stay general rather than dialed to one model.
