I immediately bought half a dozen of my long-distance runner. Can even under adverse conditions in the dark or attach snow reliable. The harness also holds strong loads. So I was able to qualify with my kids for Amundsen Race. Actually are allowed exclusively as draft animals dogs, my children were able to 120KG slide but so quickly pull over the ice that the auditors turned a blind eye. Strotz severe icing the dishes after the race could be solved relatively easily by children. So I can recommend you with a clear conscience to children Schlittenfahrer this harness.
