I bought one about 5 years ago and love it...I pack in a climber and it was a pain to carry a climber and either a fanny pack or a backpack plus the climber...By using the vest it is easier for me to carry a climber...I also use it during muzzleloader season and gun season instead of a backpack...
Plus I use it during turkey season for my calls in addition to a backpack which has my decoys in it and a seat cushion tied to it as well...
