From Spy comes the highly technical and highly comfortable Helm Tech sunglasses. They have a matte vintage white frame, with Happy™ gray green lenses that are designed to boost mood and enhance visual clarity. They also come equipped with simple to remove side shields that stay secured even when folded; that way you can block out the sun completely.
