Nocs was born at the Citadel of Excitement, with a dream of juicing every last drop of our time outside. We kept wishing we had a set of nocs enough times where finally one day we bought some. And we used them every day. Checking the surf. Exploring backcountry lines. Watching our raccoon pals emerge at night. Seeing the world differently. On a closer level.
Inspired by life at the beach, Nocs is an ode to the original seafarers and coastal pioneers. Nocs Provisions is a collective of people who are stoked to seek the unseen. To travel curiously, and to discover the best spots along the way.
The design is inspired by the seemingly symmetric yet completely unique lines of the sea and the coastal dunes where they meet. The logo is inspired by the sunset. And the packaging is plastic free.
