That’s a lot of versatility and function for some $10, so it’s a pretty great bag even if it’s not the best quality out there. But there is something you will like lightweight foldable backpack about this bag – the really long grab handles.

While all packable day packs are lightweight, not every packable backpack is an ultralight bag. There are certainly some packable backpacks that qualify as ultralight bags, but there are also packable options that add on extra details. This bag has cemented its place on our list by providing a few extra details that make it stand out in a crowd.
