Hi, my name is Scott, and I'm the owner of Climb on Indoor Rock Climbing Gym, in Wilmington, North Carolina. Today, we're going to discuss how to tie a swiss seat. If you don't purchase a harness from your local indoor gym in the case of an emergency you can use a piece of webbing to tie a swiss seat harness. The first thing we would do is tie two leg loops about four to five inches apart just using a simple overhand knot. Once you've got your leg loops tied we're going to go ahead and step into the leg loops and pull them all the way up. Then, we're going to take our two pieces of webbing and we're going to come through the leg loop from the opposite direction, and through the leg loop. Then, we're going to take these around our waist as many times as it takes to get the webbing secure and tight. Once we've got that we're going to use a water knot to tie our two pieces of webbing together to secure them around our waist. Once you've got your water knot tied securely you're going to take your locking carabiner; come through the leg loop, up through the waistband. This would be our tie-in point. Again, this takes proper instruction from your local indoor rock climbing gym or local guide. This has been how to tie a swiss seat.
