A sleeping bag may include a top flap with a head opening for the user's head to fit through and the opening may form a comfortable seal around the user's neck. The top flap may transition over the user's shoulders, transition down underneath the user's head, and extend beyond the top of the user's head. Advantageously, the sleeping bag may offer a unique way to comfortably close the top of a sleeping bag to prevent air draft and heat loss. The sleeping bag may allow users to more comfortably sleep in multiple positions, including side sleepers, stomach sleepers, back sleepers, fetal sleepers, etc. The sleeping bag may provide a soft place to lay one's head while allowing the user to sleep in a position with their hands and arms above their shoulders, while still keeping them under cover of the top layer of the sleeping bag.
