Some products earn their reputation over decades rather than marketing cycles. The Chums Glassfloat Classic has been a go-to floating sunglass retainer since the early 1990s, and it remains a best-seller for the straightforward reason that it works.

Constructed from foam-filled soft woven polyester, the Glassfloat is comfortable against the neck, quick-drying after a swim or a splash, and durable enough to hold up through seasons of regular use on the water. The foam core keeps frames weighing up to 45 grams floating at the surface, which covers the vast majority of sunglasses on the market. For paddlers, anglers, and anyone spending time around Canadian lakes and rivers, that kind of reliable flotation is worth having built right into your retainer.

An adjustable slider lets you dial in the fit for a snug, secure hold, and the design fits over most standard frame styles without fussing. At 14.5 inches long and weighing next to nothing, it disappears into your setup without you noticing it's there until you actually need it.
