One year in across 23-24 seasons, they have been great to add two to the front of the predator pack to pack the essentials when I don’t want to take an entire pack. Ample space, zippers still work, quiet enough, nice camo pattern. Currently holding a drag, knife, gloves , grunt, bleat, rattle bag, headlamp, gaiter, and misc, with some room to spare. When I attach the predator pack to the fas pack it’s two easy quick access pockets and use the empty predator pack as a dump pouch for what I take out until the end of my sit. Haven’t wanted to take them off yet!
