Eco friendly sunnies - how can that work, you ask? By replacing plastic with environmental friendly, organic materials such as sustainable woods, plant based acetate and, watch out for this, re-purposed skateboard decks!

Enter Proof Eyewear from Idaho, USA who "focus on bringing our customers unique frames made from sustainable materials".

Proof Eyewear was founded by three brothers in 2010 and got its start out of a garage in Eagle, Idaho. The inspiration of Proof came from the founders’ Grandpa, Bud. The love for wood and nature is how the idea for Proof Eyewear came about. Brooks Dame, the company’s founder, wanted to create a product that was eco-friendly and one of a kind that the customer could identify with. Proof prides itself on providing original products that are handcrafted from sustainable materials. Proof Eyewear continues to innovate and provide a wide variety of products that aren’t just environmentally friendly, but unique and original. Proof-Crafted from the Ground Up.

And besides the eco-angle, for which alone we would love this brand until the end of sunny days, we also dig their style and the cute retro-touch!
