Picture this, you're stuck on the side of a mountain, you can't go back, you can't continue but you can bail down a sketchy looking gulley. The rocks wet and loose and you've had enough, freedom awaits you at the bottom of the gulley but first you need to make it past the down climb that wants to kill you. Luckily, you have some tat and this rascal on your harness, you're saved, the climbing gods don't hate you as much as you think. You set up the sketchiest abseil of your life, you don't climb on a belay plate and rope and you make it down to safety, you've a cracking story to tell and you didn't cry on the phone to mountain rescue. Win! Will buy again.
P. S. To whoever finds this abandoned in North Wales, buy it a beer for me.
