Fight and Flight Tactical’s LLAMA pack works well without frame stays thanks to it’s semi-rigid backing but it does have the ability to accept them. It took a while but the stays are finally available. The stays should provide an extra measure of weight-transfer to the hip belt, making the LLAMA more comfortable with heavy or off-balance loads – like when there is a rifle secured in the tailgate.
They are made from aluminum and can be bent to fit your back. They are 15″ long, 1.25″ wide, and .125″ thick and sold in pairs. Pick up some frame stays for your LLAMA at Fight and Flight Tactical.
