27 models from 6 brands in this size band.
The median weighs 900 g2.0 lb at 24 L, or 37 g per litre.
Prices run $12 to $350 (12 more are priced in another currency and left
out of that range — nothing here is converted).
5 of the 6 with all three dimensions
known come in under 115 cm linear — see
the airline limits for which carriers that
actually satisfies.
Volume is the figure the brand publishes, not one we measured or inferred; bags that state no volume are not in this band or any other. Bands are exclusive at the top, so a 30 L pack is in 30–40 L and not in 20–30 L.
