Lightweight backpack

My head is empty. Occasionally, thoughts about ultra-light equipment and ways to lighten the backpack jumped back and forth. But this is not the same. The article should be about the relationship between a light backpack and the person it is riding on.

It would seem like a most fertile topic.  Why isn't anyone writing to me? The insight came at the right time - another second and I would have abandoned this idea.

As soon as the light backpack is on the back, the owner completely forgets about it. A light backpack, unlike its heavy brother, does not evoke emotions, is not thought about, and as a result is not written about.
