USGI USMC Pack System Mystery Cinch Modular Sternum Strap - New

USGI USMC Pack System Mystery Cinch Modular Sternum Strap - New

The USMC Mystery Ranch Sternum Cinch Strap (officially designated in military logistics as the Strap, Webbing [Sternum Cinch]) is a specialized load-bearing solution engineered specifically for the Marine Corps' FILBE / USMC Pack System. Anyone who has worn a heavily loaded tactical rucksack over a plate carrier or body armor knows it can be a painful combination. Typically, standard shoulder pads slide outward off the armor profile and dig directly into the armpits, resulting in severe chafing, bleeding, or localized nerve damage over extended movements.

Designed by elite pack maker Mystery Ranch and fabricated under defense contracts, this clever accessory acts as a structural anchor. It mounts directly to the front MOLLE/PALS webbing of an Improved Modular Tactical Vest (IMTV), Outer Tactical Vest (OTV), or standard plate carrier at armpit level. Once attached, it reroutes the rucksack's shoulder straps across the front chest panel. This shifts the dense payload weight off the armpits, locking the backpack squarely onto the body armor to eliminate load swaying and severe hot-spots.

This item arrives in New condition, unissued and pristine inside its original factory configuration. The high-tensile webbing, heavy-duty stitching, and quick-detach polymer buckle are completely flawless and 100% field-ready.
