I wear a camo vest suspension system with a lifeline when I go up. The vest goes over my shoulders and under my crotch and around my mid section. I wear it with my climber as well. i set it so I can't fall more than about a foot total, including the stretch.
On a related note, I share venison with a paralyzed former hunter and his family, who didn't do this and had a bad outcome. He loved the woods and archery hunting in particular. He would tell us all that we should never take safety for granted. I know another guy who dropped an arrow with broadhead on his way in to hunt. On his way out, while looking for it he tripped on it. It went through his La Crosse Burley into his calf and out again... He was found by his buddy he was hunting with and Life Flighted out and saved by the Para meds, and after several surgeries and skin grafts has almost fully recovered. That was 25 years ago. stuff happens.
I once slid down a tree when getting ready to descend after an un eventful hunt. 20 feet straight down the tree while standing there facing the trunk. I left fingernail scratch marks the whole way I swear! The slide slowed as I got closer to the ground. In total the trip took about a second/or an eternity depending upon your perspective... My lower back, already damaged in a car accident years earlier hurt for like 6 months after that. The worst part was having to go back up and get all my stuff hanging on hooks. Don't think things can't happen to you!
