All Gill sunglasses are floatable, so if you drop them, all is not lost. They feature UV protection and 100% glare free polarised lenses specifically designed for use on the water. For further protection they have 100% UV 400 protection, blocking 100% of harmful UVA, UVB and UVC radiation. One feature we especially love is the Oleophobic technology applied to the inside face which repels fingerprints, sun lotion and skin oils.
