An elastically stretchable laminate (1) includes a first non-elastic nonwoven web (2), a second non-elastic nonwoven web (4) and an elastic film (6) between the first and the second nonwoven webs (2,4). The laminate (1) has been rendered elastic in a first direction (MD) by incremental stretching and partial tearing of the first and second nonwoven webs (2,4). The laminate (1) includes a reinforcement layer (8) arranged between the first and second non-elastic nonwoven webs (2,4) and comprising unbroken reinforcement fibers or filaments (9) extending in a second direction (CD), generally perpendicular to the first direction (MD).
