U.S. Military Improved Duffel Bag (IDB) | OD Green
Haul your gear with the authentic, bombproof hauler trusted by the U.S. Armed Forces: the Improved Duffel Bag (IDB). This is the genuine military surplus transport bag (NSN: 8465-01-604-6541) in classic Olive Drab Green, representing a massive upgrade in functionality over the old-style "sea bags."
Backpack & Duffel Carry System
The most significant feature of the IDB is its versatile carry system. It includes two padded, adjustable shoulder straps, allowing it to be comfortably worn as a backpack for hands-free transport over longer distances. It also features four robust nylon handles—two in the center and one on each end—for traditional duffel-style carry and easy handling.
Rugged, Deployment-Ready Construction
Constructed from heavy-duty, water-resistant 1000 Denier Cordura nylon, this bag is highly resistant to abrasions, tears, and scuffs. The heavy-duty, self-mending zipper is designed with eyelets that can be secured with a padlock, and a small external pocket is perfect for documents or quick-access items.

Came in exceptional shape, looking almost brand new. No holes and the zipper was perfect

I ordered a bivy sac from Ron. I had questions. He responded immediately. I couldn't be more happy with his response, alleviating my concerns. His motto: "Under promise, over deliver" was validated. Highly recommend. Thanks Ron
It was bigger than I thought sent it back for a smaller one

Looks brand new!

I’m very happy with this duffel bag! It arrived even faster than I expected. Although it’s a used item, the quality is excellent—sturdy, clean, and exactly as described. A nice personal touch was the handwritten “thank you Carolina” on the receipt, which made the experience even better. Great value for the price!

Everything is top quality and ready to handle whatever you can give. After all it’s US military.

I got a Medium OCP ruck with them and it look amazing and wasn’t messed up and didn’t have a mildew smell.
