The best knee ascender design ever!!!

Dan shows you the knee ascender design he created and has been using for the past 5 years. This knee ascender design has a huge advantage over the traditional knee ascenders on the market, as this design can be left attached to the leg for the duration of the climb allowing the climber to use the knee ascender and foot ascender together on many occasions throughout the climb where necessary. Dan explains how you can make one of these ascenders yourself, and shares his experiences using the devices.
