The Bullet Belt Shoulder Harness is a substitute for the Bullet Belt UNIVERSAL BELT. It allows all of the attachments of the system to be attached from the shoulders rather than the waist. The shoulder harness is a "double-sling" design with the patented velcro tail coming down the back. This product only works with other Bullet Belt attachments. It is pictured here with the Hydro-Sled. Hydro-sled is not included at $55 price.
