The present invention includes a neck-bonded laminate and a process for forming a neck-bonded elastic laminate, the laminate including a primary elastic region and a secondary elastic region. An exemplary process for forming the laminate includes providing a necked material and overlaying the necked material with an elastic sheet. The necked material and elastic sheet are passed through a nip between two rollers, the rollers being configured to form a primary elastic region and a secondary elastic region and the secondary elastic region having higher strength than the primary elastic region.
