I think PA may have more use than Nano speedy, and both are great to keep, I have both haven’t used them, and I can see myself take PA to neighbor’s party, run to post office etc, very casual occasions that Nano speedy might be appear “try too hard” but it would be great for walking around in museums , theme parks etc if you stay in a hotel nearby has larger bags with you, hands free and can holds a lot, for more dressy occasions I have other bags to go for
