The wonderful thing about this bag system is that all the pieces can be used independently of each other. But put them all together, and you get one heck of a bag! This sleep system is made of 3 items:

The Black Intermediate Cold Weather Bag, which is rated to -10F. The anatomically designed foot box has twice the insulation as the rest of the bag. There is a sewn-in draft collar that helps keep heat from escaping from the shoulder area. Measures 87 x 35.5 inches to 87 x 23 inches.

Stuff that bag into:

The Green Patrol Bag, which is rated to +30F. Self repairing zippers, that double pull so you can ventilate from the top or bottom. Bag measures 92 x 37 inches to 97 x 23 inches.

Those two bags go into:

The Gore-Tex® Bivy Bag, made of waterproof and windproof Gore-Tex® fabric. Includes snap fastener and zipper. Bivy measures 85 x 28 x 35 inches.

When all 3 bags are zipped together, you have a bag that is rated at -40F, good for 3-4 hours.

Comes with a heavy duty compression sack that measures 30 x 14 inches, and has heavy duty straps and ladder locks.

ALL BAGS ARE USED, BUT IN VERY GOOD CONDITION! THEY MAY NEED TO BE CLEANED.
