All Ergorigs come with an embroidered set bag.
 
Classic vs. CenterFit: While the CenterFit was originally designed for operators with larger chests, we found that some other operators (regardless of body type) also preferred it. Both versions offer the same weight transfer, it's really up to you if you find the front strut more comfortable on the right or in the center of your chest when operating. When using the Undersling, the CenterFit does allow a little more space along the right side of your body.
 
Short vs Tall: Measure from your front hip point to the top middle of your shoulder. If you're less than 20" order a short, more than 20" order a tall. Your front hip point is the part that feels like the tip of the triangle in your hip on the front side that is right around your belt line. Of course there's overlap between the two sizes, so if you're right at 20" either will work. 
 
Undersling: This greatly enhances the Ergorig's capabilities by adding low mode versatility. Use your Ergorig to effortlessly hold your camera anywhere between the ground and your shoulder. Height adjustments are quick and the thick elastomer band helps to dampen the effect of footsteps. The adjustable strap-on capture-release mechanism fits onto any camera's top handle. 
 
CounterForce: While it's always better to have a balanced camera for the best handheld work, sometimes it's just not possible. When that happens, the CounterForce can pick up the slack. The optional CounterForce accessory balances front heavy cameras by utilizing an elastomer cord attached to the rear of the camera that quickly connects and disconnects to a tension adjusting cleat at the rear of the belt. It creates a balanced load without adding any weight to the camera.
