25K, some years a lot more / mostly flat in packing cubes (roll socks)

That bundle packing diagram? That's OK for a trip where you unpack once, but terrible for the way I travel, one week to 2 months with longer trips staying one week in a few places and 3-4 days in most stops. I've fully embraced packing cubes, especially the Eagle Creek Specter Tech compression cubes.

As mentioned above, one can pack day-by-day in each cube for a shorter trip and by categories (pants, tops, etc.) for others. Another big advantage of packing cubes is at the end of a trip I can compress dirty clothes in the cubes, just wash clothing and the cubes when necessary.

I've finally worked out how to travel carry-on only for long trips, even in winter. Liberating to say the least.
