KB3D Nexus Mask (MF11)

This is the MF11 Gas Mask. Also known as FMJ05 Gas Mask. It features large triangular eye lenses for excellent visibility and a bold look. Its adjustable 6-point rubber head harness ensures a secure, one-size-fits-all fit. The asymmetrical front includes a 40mm NATO-compatible side port for accessories like rebreathers or aroma inhalers.

This black rubber mask, inspired by the M15 and M65, is China's standard-issue military mask, known as the MF-11. Designed to endure CBRN threats, it combines durability with versatility for both practical and playful use.

Developed in the KB3D lab, the Nexus is The Modular Gas Mask System. Built around a universal interface—dubbed The Insert—each module screws securely into the mask’s insert, allowing the function to be changed as required.

This Nexus mask has The Insert installed and includes the KB3D Nexus Standard module. The Standard module is a key component, restoring the mask to its original configuration when no other attachments are in use. This module includes an integrated, reversible valve that recreates the correct airflow and allows the original front cap of the mask to be reattached.

All other Nexus modules are not included and needs to be purchases separately.

This is a one-size mask. The straps are adjustable to accommodate different head sizes.
