The most common mistake people make when stuffing a sleeping bag is to try to roll the bag and then stick it into the compression sack. Begin by stuffing the sleeping sack by the foot-end first. There is an issue by starting with the hood-first, leaving the tail end (where your feet go) wagging out there until the very end. The problem is that the foot box of a sleeping bag is an enclosed space, which means that it usually turns into an air-filled balloon if it’s the last thing going into the stuff sack. Hassle and inconvenience ensue as you spend time slowly forcing air out through the fabric and insulation. If, on the other hand, you start with the tail, all that air readily escapes, leaving you with the open and easy-to-stuff hood at the end. Continue stuffing by pushing in handfuls of the sleeping bag into the compression sack. Once the bag has been stuffed, you simply position the lid, use your knee to compress the bag downward, and then pull down the straps to hold compressed the squashed bag to minimal size.
