Expand Your Loadout with Confidence

Spiritus Systems The Thing 3 – Modular Chest Rig Platform

The Thing 3 from Spiritus Systems is the beefed-up evolution of their chest rig expansion line- a load-bearing powerhouse designed to carry everything you need without compromise. Whether you’re upgrading a Micro Fight setup or building a MOLLE-based rig from scratch, the Thing 3 is your rugged, modular foundation for mission-ready versatility.

With 4-column, double-sided MOLLE panels on each wing and a center MOLLE field front and back, this platform gives you more real estate than any other Spiritus chassis. Add admin pouches, SPUDs, utility, or even hydration gear without breaking your setup. Fully articulating buckles make movement easy, while quick-attach loops for placards (Micro Fight MkV, Mk4, and more) make swapping out mission profiles effortless.

This is your build-it-your-way chest rig, whether you’re attaching a Lunch Box or mounting up with three SPUDs and heading out the door.

Why We Love It

The Thing 3 is the chest rig equivalent of bringing a plate carrier to a chest rig fight. It’s structured, rugged, and built to carry like a mini war machine—without committing to full armor. It’s everything you love about Spiritus, scaled for your biggest missions.

* The Thing 3 requires the addition of a Fat Strap and Back Strap. SOLD SEPARATELY.*

Key Features:

• Fully Articulating Buckles: Each end of the THING 3 is equipped with secure buckles mounted on eyelets, allowing full articulation for superior flexibility and comfort.
• Quick Placard Attachment: A dedicated loop field and retaining loops make attaching your Micro Fight MkV, Micro Fight Mk4, or other brand placards a breeze, enabling fast, secure swaps between your chest rig and plate carrier.
• Additional MOLLE Field: The center of the THING 3 features a MOLLE field on both sides. This allows you the option to run 3 SPUD Pouches up front, or to place admin pouches close to your body.
• Modular Design: The center portion of the THING 3 can be separated to add accessories such as the SACK Pouch, Lunch Box, or Brunch Box via hook-and-loop fasteners.
