Core goes to the heart of climbing. Join an international cast of the sport's most dedicated athletes as they stick it when it matters most. Shot in 35mm Ultra High Definition, get ready to see every detail of some of the nastiest pieces of rock ever climbed. A close examination of each character offers perspective beyond just their achievements on the stone. From Helsinki to Hueco, Africa to Italy, the enclosed forests of Tuscany to the vast open space of the American West, this film is a study in the landscapes and lifestyles that define our sport. Be there, in the moment, as a 5.14 traditional route gets its first ascent. See the mind-bending footage from Livin Large, Nalle Hukkataival's monster 8C.
