摘要

A backpack comprising a support frame (20) and a collapsible sack (10) being formed by at least one wall (50), the wall (50) having inner and outer surfaces (51, 52), the inner surface (51) defining an internal compartment (53) for containing an item; the sack (10) being mountable on the support frame (20); the at least one wall (50) comprising at least three fold lines (54) along which the at least one wall is foldable so as to form at least one pleat (55); the pleat (55) is configured such that the outer surface (52) of the wall portion defining the pleat (52) is deployable so as to define an outer compartment (56) for containing an item; the at least one wall (50) being moveable between a first, extended position in which the volume of the internal compartment (53) is maximised and a second, collapsed position in which the at least one wall (50) is folded about the at least three fold lines so as to form the at least one pleat (55) and to minimise the volume of the internal compartment (53).
