U.S. Military MSS Intermediate Cold Weather Sleeping Bag
When the temperature plummets, trust the gear that's proven in the most demanding conditions. This is the authentic U.S. Military Issue Intermediate Cold Weather Sleeping Bag, the heavy-duty workhorse of the legendary Modular Sleep System (MSS). As a genuine piece of surplus (NSN: 8465-01-547-2694), this bag offers incredible warmth and durability for any serious cold-weather adventure.
Serious Cold Weather Performance
Designed as the primary cold-weather component of the MSS, this sleeping bag is rated for temperatures from +30°F down to -10°F on its own. It features a durable, water-resistant ripstop nylon shell and is filled with lofty synthetic insulation that is engineered to retain warmth even when damp—a critical feature for field use.
Part of a Legendary System
While an excellent standalone bag, its true potential is unlocked as part of the complete Modular Sleep System. It is designed to be inserted into the lighter-weight green Patrol Bag and then placed inside the GORE-TEX bivy cover, creating a layered system rated for extreme arctic temperatures.

Let customers speak for us
from 84 reviewsI 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.

Bought a lot of surplus from here. Excellent customer service and staff is fantastic. The bargin bins are a really cool feature of the store.

US Military Surplus Backpack ACU MOLLE II 3-Day Assault Pack USGI

I ordered the grade 1 - like new. I think it is new as it looks like it has never been issued or used. It's a great pack for short hikes and makes a nice overnight travel bag too. I am very satisfied with the item, the price, and the speed of delivery!
