Spiritus Systems Expander Wing Mk 2 | Low Profile Chest Rig and Plate Carrier Pouch

Built for Modular Loadout Expansion, Comms Integration, and Low Profile Carry

The Spiritus Systems Expander Wing Mk 2 is a versatile loadout expansion pouch designed to add low profile storage to chest rigs and plate carriers without adding bulk. Built for modern modular systems, it was developed to integrate seamlessly with Micro Fight Chassis, 556 Placards, and LV/119 plate carriers while maintaining a streamlined, mission ready setup.

Designed for comms gear, rifle magazines, and small essential equipment, the Expander Wing Mk 2 allows you to expand your kit in a clean, efficient way. Its ambidextrous design and compatibility with both Velcro and TUBES cummerbund systems make it adaptable to a wide range of configurations.

If you are searching for a chest rig wing pouch, plate carrier side pouch, comms pouch, or low profile mag storage solution, this delivers flexible expansion without sacrificing mobility.

Ambidextrous Design with Seamless Integration

The Expander Wing Mk 2 features a reversible design, allowing it to be mounted on either side of your kit depending on your setup. It integrates directly with Velcro or TUBES cummerbund systems, and the pass through design allows use with TUBES without removing the pouch.

An internal adjustable retention strap allows you to customize pocket depth, ensuring a secure fit for radios, magazines, and other gear. The base pocket height starts at approximately 6 inches and can be adjusted for different loadouts.

Bungee retention and dual eyelets provide additional security for radios or magazines, while maintaining quick access when needed.

A loop over strap secures the pouch to both Fat and Skinny chest rig straps, helping keep the pouch stable and reducing movement during use.
