Strike Hard Gear is working with an interesting prototype. It’s a backpack that is designed to discreetly carry a rifle but also transforms into a chest rig!
The pack is designed to hold a rifle and look relatively innocuous from the outside. The PALS webbing that can be seen on the front of the bag in chest rig mode is actually inside the bag when it is configured as a bag. This would allow the user to keep it fully configured and then just open the bag into a chest rig when necessary.
Additionally, the bag is designed such that the exterior could be a non-tactical color and the interior (which becomes the exterior in chest rig mode) could be a “tactical” color. They are also considering adding the ability to carry an armor plate.
The images shown here depict a prototype and there will likely be changes if it goes into production. Check out StrikeHardGear.com
I have a chest rig from Strike Hard. Their stuff seems top-notch.
