This is a very interesting dry bag. With its help, a thick sleeping bag can also fit into a small bag smaller than 40 Lites.
This waterproof bag can not 100% prevent the expansion of sleeping bag. It can only temporarily help you compress the sleeping bag to a relatively small volume, the compression effect can last about half an hour, before it expands you can insert it into your backpack, and the backpack will limit its continued expansion.
