The 5.11 Tactical RUSH LBD MIKE 40L is a medium-sized duffel that converts to a backpack, built from 1050D tear-resistant, water-resistant nylon with webbing reinforcements and heavy-duty bar-tacking throughout. At 40 liters (2,440 cubic inches) and 2.4 lbs, it carries armor, equipment, and mission-critical gear without adding unnecessary weight to the load. Main compartment dimensions run 11" H x 20" L x 10" W. The external MOLLE platform accepts purpose-built pouches for a fully configured kit.

Who this is for

• Law enforcement and military personnel who need a durable, configurable carry system that transitions from vehicle trunk to foot patrol without repacking
• Range and training users who carry mixed loads — armor, spare mags, medical kit — and want a single bag that organizes all of it through MOLLE expansion
• Outdoor and travel users who want a rugged, water-resistant duffel that can double as a backpack when the mission changes mid-trip

Construction and materials

The shell is 1050D nylon, a denier rating that balances abrasion resistance with manageable weight. YKK self-healing zippers run throughout, including rainfly-protected main compartment zippers that keep contents dry in wet conditions. Bar-tacking at stress points and webbing reinforcements allow the bag to carry heavy loads — including plate carriers and armor sets — without seam failure. The padded bottom panel protects contents and provides a stable base when the bag is set down on uneven surfaces.

Carry configuration and organization

The RUSH LBD MIKE ships with two carry modes built in. Quick-release adjustable backpack straps with non-slip reinforcements deploy when a hands-free carry is needed. A reinforced top carry handle and reinforced side grab handles provide short-distance hand carry. Dual side compression straps can cinch the load, attach extra cargo, or connect under the bottom panel as an alternate carry handle.

Interior organization runs through two zippered mesh pockets on the lid and lashing straps inside the main compartment. A rear zippered pocket handles items that need fast access without opening the main compartment. An ID and flag patch loop panel sits on the exterior for unit identification or personal marking.

MOLLE compatibility and expansion

An external web MOLLE platform covers the front face of the bag and accepts any PALS-compatible pouch. This allows the bag to scale from a clean 40-liter haul to a fully loaded tactical configuration depending on the mission. The MOLLE platform pairs with 5.11's own purpose-built pouches or any standard third-party PALS accessory.

Frequently asked questions

Does this bag work as a backpack or only as a duffel?

Both. The RUSH LBD MIKE includes quick-release adjustable backpack straps with non-slip reinforcements that stow away when not in use. Switch between duffel and backpack carry in seconds without removing any gear. The top carry handle and side grab handles remain functional in either mode.

Can I attach pouches and accessories to this bag?

Yes. The external web MOLLE platform on the front face of the bag accepts any PALS-compatible pouch. 5.11 purpose-built pouches attach directly, as does any standard third-party MOLLE accessory. This lets you build out the bag's external capacity without changing the main compartment load.

Is the bag waterproof or water-resistant?

Water-resistant. The 1050D nylon shell resists moisture penetration under normal wet conditions, and the main compartment zippers include rainfly protection. The bag is not rated as fully waterproof or submersible. For extended rain exposure, consider a pack liner inside the main compartment.

How much weight can this bag carry?

The RUSH LBD MIKE is engineered with webbing reinforcements and heavy-duty bar-tacking specifically to handle heavy loads including armor and equipment. A maximum load rating is not published. The bag weighs 2.4 lbs empty and holds 40 liters of volume across the main compartment and organizational pockets.

What are the main compartment dimensions?

The main compartment measures 11" H x 20" L x 10" W. Total bag capacity is 2,440 cubic inches (40 liters). This comfortably accommodates a plate carrier with plates, a change of clothes, and ancillary gear simultaneously.

Can this bag be shipped anywhere in the United States?

Yes. The RUSH LBD MIKE is a non-ballistic tactical duffel with no armor components and carries no state-level shipping restrictions. It ships to all 50 states. Contact us with any questions about your specific order.
