The ECWS (Extreme Cold Weather System) is a modular sleep system from the U.S. Military. The system is made up of 3 items - the intermediate sleeping bag, patrol bag, and bivy bag. When all 3 bags are used together they are rated for use at -40 degrees Celsius. 

This is just the patrol sleeping bag which is designed for warmer temperatures, rated at +4 degrees Celsius for a comfortable sleep. A survival temperature rating would most likely be around -5°C.

This patrol bag is the lighter of the two sleeping bags from the ECWS and is intended for warmer temperatures. The double zip can be pulled from both ends, allowing ventilation from the top or bottom. An adjustable drawstring around the hood helps retain heat within the sleeping bag. The construction is a water resistant, ripstop nylon fabric. This is genuine U.S. Military surplus, so you know you're getting a high quality sleeping bag.
