The original back-saving Ergorig!
 
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.
