Diamonds are forever and so are these tubes. Koa Smith, Alex Smith and Dylan Goodale recently went on a treasure hunt to Namibia and they returned very rich. In fact, Koa Smith may very well have nabbed the best GoPro clip in the history of narcissism (We’re sorry, Benji Brand). Alex and Dylan literally had their backs against the wall — Skeleton Bay must be the bane of a regularfooter’s existence — but prevailed with flying colors. Just press play and consider the next 15 minutes well-spent.
