The Neo Megafloat comes with an extra-large end size that is designed to fit and float larger, heavier frames &mdash up to 85g (3oz). Foam-filled quick-drying neoprene with locked-stitched ends and GripTech silicone interiors make for a retainer that keeps eyewear secure. High-vis colors and high-density foam allow for easy retrieval if your shades do end up taking a dip.
