This is general guidance. Your actual gear volume should be the final deciding factor.
What Does “70L” Actually Mean?
70L = approximate storage volume.

🪑 Capacity ≠ Comfort
Large capacity doesn’t guarantee comfortable carrying. Fit matters more.

A longer trip doesn’t automatically require 70L. Gear volume matters more.

More storage space doesn’t mean you should carry more weight. REI’s backpacking weight guide helps separate these two concepts.
