Eagle Industries has been around for a long time and that's for good reason. 

The Eagle Industries Ergo Performance System is a lightweight, performance-enhancing, belt-free load lift system to enhance plate carrier comfort. The Ergo Performance System is constructed of MIL-SPEC 500 denier nylon, Dri-Lex spacer mesh and Squadron laminate. Designed with a ventilation adjustment strap system to aid in temperature regulation, the Ergo Performance System also features four shoulder harness attachment points and adjustable bottom attachment straps for near-universal carrier compatibility. The Eagle Industries Ergo Performance System is designed with durability, comfort, and support with its padded lumbar that is rubberized fabric that reinforces abrasion points.

The Ergo Performance System has straps with tuck tabs that wrap under the plate bag and hook into the exterior MOLLE on the back to secure the bottom and has one wrap strap that wrap around the shoulder straps of a plate carrier.

The Ergo Performance System does apply pressure to the lower back. It encourages the user to stand up straighter by putting pressure on the lower back.
