The hood can be tightened with an elastic band that adapts to the sleeper's movements.

If the sleeping bag also has a thermal collar , there is a second elastic drawstring inside.

To make it easier to distinguish between the two elastic cords, the inner cord stopper for the thermal collar is round , while the outer one for the hood is square . This makes everything easy to handle even in the dark.

When the elastic band of the thermal collar is tightened, some excess band often remains, which can be annoying. There's a small inside pocket where the excess band can be stored so it doesn't get in the way while you sleep.
