In episode 4 of our series, Shop Talks, we head to the epicenter of surf & community in Northern California. Proof Lab is nestled in Mill Valley, just across the Golden Gate Bridge from San Francisco. A true reflection of the modern surf retailer, Proof Lab has been true to its core, creating a destination for the entire community. What began as a surf shop has now evolved into a multi-use facility including a surf shop, skate park, music lesson studio, coffee shop, ding repair, art studio, bio-diesel station, plant nursey and the 'Station' - Proof Lab's premium clothing retail store. We won't spoil the rest, just hit play on the video above to see what Nate has built.
