To Slackline: The Funline distinguished by their facilitated rubberized surface, which is very comfortable to walk without socks and shoes. It gives a little more grip and feels a bit "soft". With 50mm width band is about as wide, the foot is only slightly larger. This way you can be first "only" take care of the balance, making relatively rapid progress. The most fun is the practice in a small group. So you can take turns and mutually supportive btw laugh at others;)
The structure is simple: The slackline is looped with each end around a tree and tightened with the ratchet. Note here is only the orientation of the tape, as it is otherwise distorted. The included tree protection fulfills its purpose well. Should not be genut trees in the garden, you can help yourself with a ground anchor and lead the band on for example a block of wood.
In direct comparison to the classic version of the Funline is subjective somewhat more elastic or softer than the classic. I would recommend everyone to Aufprei!
