Associated to the backrest (2) of a rucksack (1) is an elastic strip (6) set in the vertical direction of the backrest (2), the strip (6) lying in a plane parallel to the backrest (2) and having its ends operatively connected to the backrest (2) in such a way that a deformation due to bending of the backrest (2) according to the dorsal arch of the user generates an elastic reaction of the aforesaid strip (6) tending to cause the backrest (2) to return into the undeformed condition so as to favour correct resting of the rucksack on the spine of the user.
