Klättermusen's harness load transfer system is based on the principle of carrying on your bones, not your muscles. The Butterfly Bridge implements a load transfer system that, rather than the conventional solution, distributes the load over a greater area.
By placing the load on the bony pertrusions, you avoid constricting the circulation in your muscles to allow them to move more freely. This results in less pain and tiredness since your circulation can work unimpeded.
The Butterfly Bridge system is especially helpful for trekkers in supporting heavier loads.Show selected equipment with Butterfly Bridge
