Handmade wood sun glasses with unique shape to your head. HB Holzbau is a Swiss eyewear brand build by Marco Zimmermann with his roots in Zermatt. When he was not skiing he was taught by his grandpa to work with his hands in wood. With his knowledge that he learned in the workshop those early years, he is today designing the best technical wood glasses on the market. We at Kask felt the connection with HB Holzbau of skiing passion and making products with quality and pride. We are now launching our co-lab with the Egon style. Frame: Wood Palisander & Maple. Lens: Green Carl Zeiss CR-39, VLT 15 % Category 3. Hard case and protection bag included.
