The products of the American company Matbock are a wide range of tactical equipment including, among others, several types of tactical stretchers, waterproof bags and backpacks for navy operations and a camouflage system for smaller equipment pieces called SKINS.
This time Matbock offers an item called the Strap Claws set - an organizer/system for attaching backpack straps to tactical vests.
The set is attached to MOLLE straps on the front of the vests/plate carrier and it holds the backpack's straps in place without the need for an additional, and extremely popular, sternum strap. The kit allows you to quickly remove the backpack without having to remove an additional strap and perform additional actions to remove it.
The Strap Claws provide freedom of movement and enough stable space needed to properly rest the weapon on one's shoulder. The Strap Claws kits are available in green (OD) with MATBOCK skins (MultiCam and black) in every package.
The Strap Claws are available for 35.00 USD per set.
