BALANCING 30 metres above ground, these slackliners take the expression of living dangerously one step further, by tightrope walking NAKED. Crossing a 61 metre stretch, the brave adventurers leave their clothes behind and wear only a single safety rope secured tightly around their waists, ankles, and in some cases - even their private parts. These risqué photographs were taken by Philadelphia photographer Jared Alden, 31, after his love of traveling and adventure merged into his passion for photography. Captured at an unknown slacklining location in the remote Utah dessert, these photographs show thrill seekers getting their kit off for the ultimate slacklining experience at the GGBY highline festival.
