RE: I want to keep ONE person safe.......
I just got one this year and used it for the first time last week on my first hunt of the year. I got the SOP fastback, and like the vest, it is easy to put on once you know how.
The great thing is that it is easier to put on than a "safety strap" once you get in the stand, it gives you more maneuverability and won't make hardly any noise becausea rope goes around the tree and not a noisy thick strap.
All you do with the $50 or so FastBack is, BEFORE YOU LEAVE TO GO HUNTINGbut after you have yourTshirt and pants on, put the shoulder straps over your shoulders. Then buckle the waist strap by inserting the smaller buckle through the slot in the bigger buckle, then put on each leg strap the same way, smaller buckle through bigger buckle. That's it. It literally probably takes less than 20 seconds to put it on, and another 20 seconds once you are in the tree.
