What is Cabin size fold?

A cabin size fold means the folded product fits the cabin baggage limits an airline sets, rather than needing to go in the hold. It is the difference between travelling with it and checking it. Babyzen states cabin size fold as yes, and Bellini does the same for its compact auto folding stroller. Because airlines set their own limits, measure the folded product against your airline's rules before you rely on the claim.
