I am sure everyone has had that moment where they feel their horse get a little tight and you grab a deep seat and whatever else you can grab...well the OS (Oh sh*t!) Handle was designed to be attached to the back D Ring of your saddle and is great in that moment to grab and brace against to  help you keep your seat.  These are double braid polyester yacht rope so soft but durable and rot resistant.  They come in 50+ color options.
