A drawstring footbox is a bottom closure at the foot of a sleep system that has a drawstring that can be opened up. This can be a nice feature for some people. First off, it provides a venting option. If a sleeper becomes overheated, all they need to do is reach down and open the drawstring to provide airflow or even stick a foot out. Second, this type of footbox can allow the user to literally get up and walk around in their sleep system by opening the drawstring and slowly shuffling or by pulling the bottom up around the waist for more freedom of motion. Getting into your sleep system can sometimes be the highlight of the day. For folks who have camp chores to do this means being warm and cozy as soon as you get to camp instead of waiting till bedtime.
