The Gill Glare Sunglasses are floatable, so if you drop them, all is not lost. They feature 100% UV 400 protection, blocking 100% of harmful UVA, UVB and UVC radiation. These glasses have Hydrophobic outer coating which sheds water and reduces salt residue for clear vision. What we love most about the Gill glasses is the Oleophobic technology which has been applied to the inside face and so repels fingerprints, sun lotion and skin oils.
