Double sleeping bag + one sided zip = bad.
12 July 2018
This sleeping bag has a major problem. It only zips on one side (and the bottom). So if the person sleeping on the side away from the zip needs to get up in the night there is no way to get out of the sleeping bag without waking the other person.
In addition, we are having a heatwave at the moment, and my wife and I have different temperature bodies. I need to be cooler than she does. With a zip on each side we could each peel back our side to let some cooler air in. But with only one zip, for the person on the opposite side from the zip to get any cool air, the other person needs to be almost completely exposed.
