Hopsooken makes gear for travel. Their line includes a backpack, neckpouch, and money belt. I’ve spent a couple of weeks with their 30L backpack, which seems to indicate that their line is good for travel, in that it’s collapsible into a small pouch, water resistant, and light. I haven’t spent time with a backpack in a couple of decades, so at this point I’m pretty close to a clean slate. Here’s how things actually shook out for me, using their model that’s black with gray trim.
