Verified reviews

"Feel far more expensive than they are. The metal arms make them. Got the brown and the black in the two-pair deal."
"Wore them all holiday in Ibiza. Zero glare off the water, case survived the suitcase. Already ordered a second pair."
"Great lenses for the price. Slightly snug on a wider face, wish I'd checked the fit class first. Swapped free within 30 days."
