Reusable outer cover for an absorbent article

A reusable outer cover for forming an absorbent article wherein an absorbent insert is adapted to be detachably attached to the outer cover, the outer cover having a front portion to be directed towards a front of a wearer, a back portion to be directed towards a back of a wearer, and a crotch portion extending between the front portion and the back portion, the outer cover extending along a longitudinal central axis, and along a transversal central axis, which is perpendicular to the longitudinal axis, the transversal central axis dividing the outer cover into a front half and a back half, and a thickness axis is defined perpendicular to both the longitudinal and transversal axes, wherein inward direction is defined along the thickness axis being the direction towards a wearer when the outer cover is worn, and an outward direction is defined along the thickness axis being the direction away from the wearer when the outer cover is worn,

• the outer cover comprising a chassis portion extending along the longitudinal axis from a front chassis edge forming part of the front edge of the outer cover to a back chassis edge forming part of the back edge of the outer cover,
• the chassis portion comprising a first chassis side edge and a second chassis side edge respectively extending between the chassis front and back edges of the chassis portion, on opposite sides with respect to the longitudinal axis, wherein,
• in at least one out of the back half and the front half of the outer cover,
• the outer cover comprises
• a first and a second side portion extending transversally on opposite sides of the chassis portion with respect to the longitudinal axis, wherein each of the side portions of the outer cover comprises one or more waist attachment elements to attach the outer cover around the waist of a wearer during use, the first side portion is permanently attached to the chassis portion along a first side attachment segment of the first chassis side edge, and the second side portion is permanently attached to the chassis portion along a second side attachment segment of the second chassis side edge, the first and second side attachment segments defining a side portion length from the longitudinal ends of each segment closest to the central transversal axis and to the adjacent back edge or front edge of the outer cover,
• and
• the chassis portion comprises a main member and a flap member, the main member forming the front or back chassis edge, the first chassis side edge, and the second chassis side edge in the front or back half, and
• the flap member being arranged with an outward facing side of the flap member facing an inward facing side of the main member so as to form a pocket between the outward facing side of the flap member and the inward facing side of the main member,
• the flap member being permanently attached to the main member along a first flap attachment segment of the first chassis side edge and along a second flap attachment segment of the second chassis side edge, the first and second flap attachment segments defining a waist region length from the longitudinal ends of each segment closest to the central transversal axis and to the adjacent back edge or front edge of the outer cover,
• wherein the side portion length extends by a longitudinal distance beyond the waist region length in the direction towards the transversal axis.
