Photos: the world's sickest slacklines

Slackliners are taking their sport to new levels – and new locations. Don't look down...
By Josh Sampiero

There's nothing lazy about these 'slackers', but to the unitiated, they certainly look crazy. The niche sport has risen to new heights as balance experts tie up open-air traverses in incredible new places. Below, we showcase some of the best images we've seen. Photographer Krystle Wright shares some of her favourite shots along with a few from climber and slackliner Hainz Zak. Then there's a selection from this year's Red Bull Illume Image Quest, and one epic moon-lit shot from climber Dean Potter.
