The Ruffwear Slackline Leash picks up the slack so you don't have to! With this adjustable length leash, you can make the leash longer or shorter, depending on your surroundings. An ergonomic metal slider allows for easy one-handed length adjustment on the go - from 3.5 ft to 6ft. A side release buckle near the handle converts to a waist-worn option for hands-free walking and running. Or use the side release buckle to quickly clip around a tree or post.
