This poly webbing harness is designed with adjustable straps to fit just about any size. If a single model fit is desired, the straps can be trimmed easily as is shown here.
The webbing itself is one inch wide and has a breaking point of 600 pounds, so it is extremely secure yet comfortable to wear.
The straps are stitched strongly in place and attached to dually adjustable straps for optimal placement of the buckle.
