1. A shoulder strap system for adjusting the length of a shoulder strap using a single hand, the shoulder strap system comprising:
a tri-glide slide having a pair of side members spaced apart from one another, first and second end bars each attached to and extending between the side members at opposite ends thereof, and a center bar attached to and extending between the side members at a position between the end bars;
a pull attached at a first end to the center bar and terminating at an opposite, free second end;
a shoulder strap, the shoulder strap having a first strap section of a length of strap and a second strap section of a length of strap, the first strap section having opposite first and second ends, the second strap section having opposite third and fourth ends;
a ring attached to the first end of the first strap section and the second end of the first strap section adapted to attach to a device to be carried by a user;
the third end of the second strap section being looped through the ring and secured to the first end bar, the second strap section being threaded through the tri-glide slide such the first and second end bars are disposed along a first broad face of the second strap section and the center bar is disposed along a second broad face of the second strap section which is opposite the first broad face the second strap section; and
the fourth end of the second strap section adapted to be attach to the device;
wherein a length of the shoulder strap, as measured between the second end of the first strap section and the fourth end of the second strap section, is adjustable by pulling on the pull in a direction either toward the second end or the fourth end to move the tri-glide slide in the same direction; and
wherein a friction between the first end of the pull and the first face of the second strap section prevents the tri-glide slide from moving without pulling on the pull; and
wherein the first end of the pull wraps around the center bar.
