Frequently Asked Questions

How does the Spiritus Systems Assault Back Panel Core Mark II attach to a plate carrier?

It uses a 'fang' attachment system with two midline top tabs and two outboard bottom tabs that interface with the carrier's PALS webbing. Integrated zippers on the panel also connect to the carrier's rear plate bag for a secure fit.

What are the key new features of the Mark II compared to the Mark I?

The Mark II introduces a single vertical MOLLE column between the zippers for accessory mounting, utilizes Xpack material for water repellency on the interior, and features an improved integral beaver tail secured by buttons instead of G-hooks.

Can I use my old Spiritus Systems flaps with the new Assault Back Panel Core Mark II?

Yes, the Assault Back Panel Core Mark II is designed to be backwards compatible with all existing Spiritus Systems flaps, ensuring you can continue to use your previously purchased accessories.

What is the purpose of the adjustable zipper system on the back panel?

The two YKK zippers allow you to adjust the interior volume of the back panel. The outermost zipper provides full expansion, while the secondary zipper can be used to collapse the internal space when less volume is needed.
