I have often thought about the dire situation a fall may bring in a sans medical treatment facility scenario. In the western novel Jubal Sackett, by Louis L’Amour, Jubal finds himself in the wilderness with a broken leg and cursing himself for not being more careful.
Though the article references falls from structures, I thought the ability to tie a Swiss seat may help an individual in either an urban or wilderness environment. ITS Tactical puts out a great knot tying series on YouTube, and the Swiss seat may be a quicker and cheaper alternative to purchasing a harness or just going without one. I hope this is a help. – Jeremiah Johnson in Florida
