A shooting harness is described in which a back member is supported by shoulder suspension members from the shoulders and across the upper back region of a shooter. A leg restraining member extends from the back member and includes at least one knee segment positioned to engage at least one of the shooter's legs in the vicinity of the knee with the shooter in a sitting shooting position. The back member and leg restraining member together form a shooter encircling loop that provides a substantially stable brace about the shooter's upper back, torso, and at least one knee to stabilize the shooter in a sitting shooting position.
