Vanquest FATPack-Pro LARGE B-Side Insert

The Vanquest FATPack-Pro LARGE B-Side Insert (LB01) is a tear-away hook-and-loop organizer insert measuring 13.5" (H) × 9.5" (W) and weighing 8.6 oz (244 grams). Three semi-transparent vinyl mesh zippered pouches (8.5" W × 3.75" H × 2.25" D) with content label windows provide enclosed, category-specific storage for medical or EDC supplies. It attaches to any loop-lined surface and removes in a single pull for rapid transfer between packs or standalone deployment.

Trusted by first responders, military medics, and tactical operators. The LB01 B-Side Insert is the enclosed-storage component of the FATPack-Pro LARGE organization system, purpose-built for injury-specific category loading where enclosed pouches with positive content ID prevent item loss and enable fast, stress-proof access during trauma care.

Who Uses This & When

• FATPack-Pro LARGE users: The LB01 is the factory B-Side Insert for the FATPack-Pro LARGE — replacement or additional inserts allow maintaining multiple pre-staged mission-specific loadouts.
• 18D and combat medics: Pre-loads the LB01 with injury-category packs (hemorrhage, airway, circulation) and transfers the loaded insert between the FATPack-Pro LARGE and a loop-lined staging bag at a CCP.
• Mass casualty incident staging: Multiple LB01 inserts pre-loaded with identical supply sets allow rapid, consistent triage kit distribution to rotating responders at an MCI.
• EMS training programs: Instructors pre-load LB01 panels with scenario-specific supplies and swap them between student packs between training iterations.
• Wilderness expedition medicine: Organizes drug/medication, wound care, and patient assessment supplies in three distinct semi-transparent pouches for field identification without digging.

How It Compares

Generic internal organizer bags use fixed compartments with no positive ID system. The LB01 provides three indexed semi-transparent pouches with content label windows, enabling full inventory confirmation without opening any zipper. The tear-away format is a design capability unavailable in sewn-in organizers: a loaded LB01 transitions from the FATPack-Pro LARGE to any loop-lined pack in under five seconds. This modularity is the core Vanquest design advantage — the pack organization travels with the medic, not with any single bag.

Frequently Asked Questions

What packs is the LB01 LARGE B-Side Insert compatible with?

The LB01 attaches to any loop-lined interior or compartment. It ships as the B-Side Insert in the FATPack-Pro LARGE but is also compatible with any Vanquest pack with a loop-lined compartment sized to accommodate 13.5" (H) × 9.5" (W), as well as compatible third-party loop-lined bags. It is not sized for the FATPack-Pro SMALL interior, which uses the smaller SB01.

Can the LB01 be used as a standalone organizer without a pack?

Yes. The rear hook panels allow the LB01 to attach to any loop-lined surface — a cot-side loop panel, a medical cabinet, a MOLLE vest panel, or any hook-and-loop compatible mount. The dual reinforced top grab handle enables it to function as a standalone tear-away organizer deployable at a casualty collection point or treatment station.

How does the LB01 differ from the SB01 for the SMALL pack?

The LB01 measures 13.5" (H) × 9.5" (W) with three larger pouches (8.5" W × 3.75" H) and weighs 8.6 oz; designed for the FATPack-Pro LARGE. The SB01 measures 12" (H) × 8.5" (W) with three smaller pouches (8" W × 3.25" H) and weighs 7.8 oz; designed for the FATPack-Pro SMALL. The LB01 pouches hold more volume per compartment and can accommodate larger supply items.
