Proof got its start in a garage in Eagle, Idaho in 2010. Founded by three brothers, Proof grew to an internationally known brand that is loved the world over. The roots of Proof begin with the founders’ Grandpa Bud. He opened his small sawmill almost 60 years ago. Despite setbacks, Bud’s small business was able to prosper with a lot of hard work and tenacity; he eventually grew that small sawmill into a nationally recognized company. Bud’s work ethic was instilled in Proof’s founders, they grew up with “sawdust in their veins” working with wood in the mill. They pride themselves on providing original products that are handcrafted from sustainable materials. Proof Eyewear continues to innovate, providing a wide variety of products that aren’t just environmentally friendly, but unique and original. Proof-Crafted from the Ground Up.
