Compatible with all of Stone Glacier's R3 Military Frames, the R3 3-Piece Belt provides excellent comfort and support. The lumbar pad is removable, allowing users to customize the belt's fit by adding, removing, and shaping the foam. The layers of foam can be trimmed and moved vertically to make a roll in the pad at any level to match a preferred curvature or thickness. The lumbar pad has a non-slip fabric integrated into the design to help the belt lock into your back while carrying heavy loads.
