A method of folding pants is suitable for use with discrete articles including mechanical fastening components and suitable for the manufacture of prefastened and refastenable pants. The discrete articles define leading and trailing halves with opposed side panels. The leading side panels can be maintained separate from the trailing side panels during folding and until the discrete articles are downstream of a folding nip.
