The US Military Modular Sleep System is one of the most impressive sleeping systems in service today. Taking input from soldiers, extreme outdoors enthusiasts, and industry professionals the military created a sleeping system that is truly designed for all four seasons. The modular design of this sleeping system allows you to use the sleeping system in layers to address the specific degree of warmth you need.

At the heart of the modular sleep system is the Intermediate Cold Weather Sleeping Bag which alone is designed to operate in temperatures from 30 degrees to minus 10 degrees. With the included Patrol Sleeping Bag you are covered during warmer months which has a rating from 50 degrees to 30 degrees. When snapped together, both of these sleeping bags are designed to keep you warm in temperatures as low as minus 50 degrees. You can fit both of these sleeping bags into the included water proof bivy bag to give full protection from the rain and wet ground for even more performance from the modular sleep system. Rounding out the system is the black compression bag which will allow you to safely store and transport the modular sleep system when it is not being used.
