One of the major problems with our old shoulder straps was adjusting the straps without taking everything off of the frame. Now, you undo the velcro , shift the strap up or down with 3 open spaces in between the upper and lower strap and tighten it down . For those with asymmetrical shoulders from years of shooting bows, you can still independently adjust your straps . Laser cut material over the sternum straps let you hang radios or in reaches and the holes will accept 1/8” bungie for securing tops of bottles or radios in place.
