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.

Let customers speak for us
from 110 reviewsGreat selection and fashion shipping. Surplus at its finest.
Product exactly as described. Has that surplus smell. Fast shipping. I will definitely buy from again.
Although "Unused" is the highest product rating at FCS, no Bivvies in that category were available. I got the "Very Good/Excellent" instead. It is high into the "excellent" end - no visible wear whatsoever, all "functions" intact, clean and ready for action. I don't know if it got washed or what, but it also had no trace of the old, milsurp "I've been stored in a mildewy warehouse the last 18 months (or years!)" stench. Smelled like...new GoreTex. Speaking of which - You're never gonna find an actual GoreTex bivvy in the civvy market for less than $150, minimum. Great deal, good service, happy customer.
Looks brand new. They even let me pick the color I wanted. Very pleased.
I've finally run across a local, credible, trustworthy company. Where have you been all my life? Product arrived in days, not weeks. Product was in better condition then I expected. Looked brand new. The handwritten note was the closer. We share a common loss and I'm happy to see you pushing thru, it is so difficult.
Carry on
Great stuff, usually much better than description and if not, they have great customer service. I am generally a really grumpy old man with a terrible attitude but I have not been disappointed by Forest City Supply products or customer service on the rare occasions its needed (but they are quick to respond and reconcile any problems!). The world may be going to hades but I will do it well equipped. I highly recommend them.
Order arrived on time and in good condition
Both the intermediate cold sleeping bags & the bivy covers conditon were better than anticipated
The Ruck appears to be a new one. I was expecting a used one. The price was well worth it.
Saw this brand new woobie and added it to my cart without thinking. Heard these had been found and other surplus sites have them listed for way more. No wonder they sold out so fast. Definitely a new favorite site.
Great deal on a perfectly good pack. Condition exactly as described with one small tear that doesn't impact functionality at all. Can't believe the prices these guys have with fast shipping as well. Recommended to a ton of friends who also picked some up. Will continue to use going forward for surplus needs.
Shipping was super fast, and the description of the item was spot on. Very happy with my purchase.
My son's should be here very soon.
I expected pretty used gear. They don’t appear to be used at all. And the shipping was quick.
