Actually its a new Slackline Brothers product .
Its called the Hogtie™ Highline Leash System.
Add a Hogtie™ to your highline leash an walk steady.... When the hog goes, it goes!
Don't be trippin! use the Slackline Brothers velcro Hogtie™ to keep the leash out of your way so you can focus on the walking instead.
two in a pack.
