In 1968, just two years after Bruce Brown practically invented the charming, adventure narrative meets documentary genre with “The Endless Summer,” a group of five friends set off to make their own, traveling, skiing, surfing, and climbing from Ventura, California, down to Patagonia, to climb Cerro Fitz Roy. The group consisted of Yvon Chouinard, Doug Tompkins, Chris Jones, Dick Dorworth, and Lito Tejada-Flores. The film they made, much like The Endless Summer, sparked thousands of adventure trips by restless explorers around the world.

Chouinard had been selling climbing gear for about a decade by this point, but was still a handful of years out from opening his first store, Great Pacific Iron Works, in Ventura. He wouldn’t have known that his philosophy of building things to last, using the best materials, with an eye toward production that did minimal harm, all in the name of pursuing meaningful adventure, would one day spawn a billion-dollar business. Chouinard was just doing what he wanted to do.

This film in many ways set the tone for Patagonia as a brand. Is dirtbag debonair a term? If not, it should be. Chouinard and crew travel in style, definitely appreciative of the good and finer things in life, but they do it cheaply, and always, always pondering the philosophical implications of what they were doing, and what the rest of the culture at large wasn’t doing. Reminiscent a bit of the bohemian beatniks that had blazed across the cultural sky a decade earlier.

The film helped set a tone for the modern adventure film. Closeup shots of wistful stares at the ocean, at mountains, at forests, each landscape whistling past the face of one of our intrepid travelers, wind mussing their hair as they stick their head out the van’s window. Ponderings of the meaning of adventure. Of travel. Of why we do the things we do. All of which are pretty much standard these days in adventure cinema.

Plus, the soundtrack kicks ass.

Whether or not it’s a gesture of goodwill by Patagonia, knowing many of us are confining ourselves indoors, rearranging our gear, some of us literally climbing the walls, or whether they’d picked this date all along to release the film, “Mountain of Storms” is now available, for free, to watch online. For how long? We have no idea.

But put on a parka, or a wetsuit, maybe, surround yourself in a pile of gear, strew some maps about, and press play below. Happy quarantining.

To get better acquainted with how Chouinard’s early life gave rise to Patagonia, but also about how one can turn activism and an appreciation for good gear into a business, read his book, “Let My People Go Surfing: The Education of a Reluctant Businessman.”

And when was the last time you watched “The Endless Summer,” anyway?
