Jack O'Neill is someone we won't forget, even if we have never had the privilege of meeting him in person.

The neoprene wetsuit pioneer was a humble and generous individual, always ready to start anything from scratch. "I Knew Jack" is an emotional tribute to one of the first icons in the history of surfing.

The clip was directed and produced by Peter Hamblin and reveals the essence of a man who introduced the concept of the surf shop and allowed us to surf more, even in cold waters. Thank you for your life, Jack O'Neill.
