The most critical piece for proper sizing is the backplate,which is available in three sizes.BackplateThe standard backplate is 17" (43 cm) long from the bottom of the waist belt to the top of theplate. The waist area is 24" (60 cm) long from end-to-end of the hip pads and the length of theactual waist webbing is 72" (182 cm) total. The standard plate is used on all men's sizes fromlarge to XXL. The plate can be easily identified with two sets of 3 grommets for mountingdoubles or aircells.The medium backplate is 15" (38 cm) long from the bottom of the waist belt to the top of theplate. The waist area is 24" (60 cm) long from end-to-end of the hip pads and the length ofactual waist webbing is 72" (182 cm) total. This backplate is used on standard women'ssizes from medium to XL. The medium backplate has two sets of 2 grommets for mountingdoubles or aircells.The petite backplate is 15" (38 cm) long from the bottom of the waist belt to the top of theplate. The waist area is 20" (50 cm) long from end-to-end of the hip pads and the length ofactual waist webbing is 60" (152 cm)total. This plate is used for women's petite sizes XS andSmall. Shoulder PadsThe shoulder pad length determines the size of the harness because it terminates on thechest at the pivot point for the chest strap and sideplate straps. T-shirt size is normally a goodindicator of what size shoulder pad is needed for an optimal fit. A size change on the shoulderpads is two inches (5 cm) from size to size.For men, shoulder pads should terminate on the chest around the nipple line. If you are inbetween sizes, it's easy to adjust the shoulder pads by moving them forward one inch (2.5 cm)(directions are in the manual). If you need to adjust it 2 inches (5 cm) or more you shouldmove up a size. Remember, moving up a size is only changing the shoulder pad length. For women the shoulder pad should terminate just above the bust line for a proper fit. Sideplates with Adjustment StrapThe sideplate is on the waist belt and its positioning is very important for fit and comfort. Toofar forward and you lose the hip support of the backplate, too far back and you may not haveenough adjustment strap and the harness may feel too small. The average fit for thesideplates is to have them covered by your arms when they are by your side. This isapproximately 2" (5 cm) behind the belt loop on the hip pads. Larger waist lines may need toshift this forward but never move it forward of where your arms are when by your side. All harnesses leave the factory adjusted for average fit. You may need to do someadjustments to get the most comfort and stability.
