Best forLight packers who want a thin underseat bag for a tablet, snacks and documents.Travellers who want a fuller day bag and are flying where the personal item limit is generous.
Watch out forSmall by design; a full load will bulge past the thin 13–16 cm depth limits.At this size it will not meet the strictest personal-item limits unless soft-packed.

Our take

The 13L is the one to pick if your airline’s personal item is thin. The 20L is a better all-round day bag but is more likely to be too deep for the strictest underseat limits.
