U.S. Military ECWCS Gen III Level 7 Primaloft Trousers
When facing the most extreme cold, trust the gear issued to the U.S. Army's elite. These are the authentic Gen III ECWCS / PCU Level 7 Trousers, the ultimate outer insulation layer designed for static operations in arctic conditions. Filled with advanced PrimaLoft® synthetic insulation, these pants offer an incredible amount of warmth while remaining lightweight and highly compressible.
Maximum Warmth, Minimum Weight
Often called "puffy pants," this Level 7 layer is engineered to be worn over all other layers, providing a final barrier against the cold. The PrimaLoft® insulation mimics the properties of down but retains its warmth even when wet, a critical feature for field use. The water-resistant ripstop nylon shell helps shed snow and moisture, protecting the insulation within.
Designed for Functionality
These trousers are built for practicality in harsh environments. Full-length side zippers on each leg allow you to put them on or take them off quickly without removing your boots. An elastic waist with Velcro adjustments provides a secure fit, and reinforced knees add durability for high-wear areas.

Let customers speak for us
from 85 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.

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!
