I have spent the better part of the last three years sleeping in this new modular sleeping bag system. I really like the new system for many reasons. The old sleeping bags were very susceptible to water and took up too much room in or on your ruck (back-pack). If your sleeping bag ever got wet, you were in for a miserable night. This new Gortex® sleeping bag system is waterproof. I have not been wet at anytime since I started using this sleeping bag. I have used it all over the world. As anyone one can tell you who has ever been in a wet sleeping bag, it is something you will not soon forget!
The sleeping bag is an all weather bag and in my opinion one of the best on the market today. Over the last few years technology has made it possible for manufactures to create lighter sleeping bags that take up less and less room. This makes life a whole lot easier for the soldiers as well as hikers, adventurers and campers. This sleeping bag comes with three parts and a compression bag. The outer shell is a Gortex® bivy bag. This waterproof bivy bag is awesome. It keeps you dry in nearly any climate. Dew will not penetrate this bivy. It also acts as a windbreaker and dust or dirt barrier. Furthermore it’s the first layer that keeps the cold and wet out, and your body heat in.
The next layer is the patrol sleeping bag. This inserts into the Gortex® shell and snaps in place. It’s made with rip stop nylon with a water resistant finish, Polargard®. This insert has an adjustable hood and zipper. This with the shell is designed to keep a soldier warm in climates down to 30 degrees. Finally you have the intermediate cold weather bag. This bag inserts into the patrol bag. This sleeping bag is also made with rip stop nylon and Polargard®. This bag is good to -10 degrees when used without the patrol bag. It is extremely warm. It is made of Polargard ® HV, hollow continuous filament resin bonded polyester.
The last part of this modular system is the Compression stuff sack. This stuff sack has a cylinder shape and is also water resistant with a urethane coating. This compression sack is really neat. I had never used one before, so I found the new goodie particularly handy and neat! Once your sleeping bag is all put together, you just grab the bottom of the bags, including the Gortex® shell and simply stuff it in to this sack. Once the bags are in the sack you draw the closure shut and lock it sing the barrel lock. Then you start cinching down the side straps using the ladder lock buckles. I would generally cinch the U.S. Military Modular Gortex® Sleeping Bag System down to the size of a football.

I really like the U.S. Military Modular Gortex® Sleeping Bag System. It is a very welcome addition to the military gear of the U.S. soldier. The soldier is set up for all four seasons with this new bag. I have spent a Winter in the high desert of Utah and a Summer in Iraq with this bag. The temperatures ranged from -30 degrees to +117 degrees. I have purchased my own U.S. Military Modular Gortex® Sleeping Bag System to use in the civilian world. This is a great all a round sleeping bag. When you use both sleeping inserts inside the Gortex® bivy, you can keep warm is some very cold climates. I do not think you can beat this bag for the price. Unless you are going to do some very serious mountaineering / climbing or go to one of the Arctic regions, this sleeping bag will work for you. This sleeping system retails for around $250.00 to $399.00, you can shop around and find some the better prices.I give this excellent sleeping bag five of five stars.
