Sizing Information
The Ergovation™ sit harness features a revolution in both fit and design. Due to the patented
adjustable work positioning “D” rings, the load bearing webbing that hosts the “D” can be adjusted to
fit a range of sizes from 24” waist all the way to a size 44” waist! What this means is that the user
can adjust the “D” pieces to create a customizable fit never before seen. The back pad design is size
specific to the end user, however it can accommodate a range of up to 3 different waist sizes per
each back pad.( For example a size Medium back pad can accommodate a size 32in., 34in., and
36in. waist.)
When measuring the waist, measure slightly below where pants are typically worn.
(Note: Be sure to allow for wearing of heavy clothing in colder months.)
In order to obtain a customized fit the user should size the back pad to their own body. The wings of
the back pad should wrap around the front of the hips by about 2-3in. (5cm-7.6 cm) to allow for
adequate adjustment of the work positioning “D” rings. If the wings of the back pad sit flush with or
behind the hip area, the user should go up one size, to allow for adequate adjustment, and
maximized comfort.
(Note : Addition of the lumbar support can affect sizing, place lumbar pad in back pad pocket
before sizing to see if fit is adequate)

according to waist size.

Warning
Abdominal Stabilization System is for support and comfort only, do not over
tension to increase snugness of fit!!
If stabilizer is too loose or tight you may need to go up or down a size in the
Back pad or loop side (J short, medium or long) of the stabilizer.
When attaching the elastic Abdominal Stabilization System: tighten the
abdominal muscles by tightening the abdomen as if you were doing a crunch,
then secure the Velcro®. Be sure not to hold your breath when you fasten the
Velcro®, as this will cause over-tightening.
If abdominal stabilizer loses its elasticity over time replace with new stabilizer
