M4 MAVERICK™ BIFOLD RAIL WALLET

The M4 Bifold Wallet was built for those who want the familiarity of a traditional bifold without giving up the strength, security, and modularity of modern EDC gear. Designed as the successor to the M1 Bifold and based on the proven M4 Wallet platform, this wallet is engineered around a CNC-machined aluminum chassis that serves as the backbone of the carry. Dango’s rail system locks components in place while allowing compatibility with select M4 accessories, ensuring the wallet evolves with your carry. At the center of the chassis is a hidden internal pocket, ideal for folded cash, coins and small everyday essentials you want kept out of sight. Premium leather or DTEX exterior panels are mounted to the frame for durability and a broken-in feel over time. Two additional interior pockets increase organization while maintaining a slim profile, allowing the M4 Bifold to carry 11–13 cards depending on thickness. A durable glass-filled nylon clip keeps the wallet securely closed during daily movement. Available in DTEX, Whiskey Brown Leather, Rawhide Leather, and Jet Black Leather, the M4 Bifold is built to handle everyday use—on the job, on the road, and everywhere in between.
