Parachutes which have a generally circular skirt or hem, such as semi-hemispherical, extended gore, or any variant of axisymmetric parachutes and cruciform parachutes with arms attached are disclosed with a plurality of vertical slits located in a circumferential band adjacent the skirt or hem of the parachute to prevent canopy inversion. During deployment, when the outer portion of the canopy is exposed to air flow, the slits open up and the drag of the skirt of the canopy is reduced, thus limiting the potential for hem migration. The slits are positioned to allow airflow therethrough in order for the pressure on the outside of the canopy to be transferred through the slit openings and released or transferred to inside of the lower section of the canopy. Instead of slits, elongated narrow openings can be utilized.
