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.

Which maker is missing? The index grows from public product feeds, so a link to where they sell is the fastest route from this box to a crawl — but the name on its own is enough.

An address here is used once, to tell you if the brand lands. It joins no list and gets no other mail — a price watch is the thing that does, and that is a separate box on any bag's page.
