Alio X GD1 is a square combination frame in grey. An updated rendition of our beloved Alio, Alio X GD1 is a semi-rimless design crafted of titanium metal and features logos and temple tips presented in the 2021 Collection. This frame is also highlighted by the metal accents on the endpieces and fitted with 99.9% UV protection and clear blue light filtering lenses. The pattern for each product will vary due to the nature of the acetate production.
