A garment made of plastic film of the type and thickness often used for the manufacture of grocery sacks and garbage bags is disclosed. Stretch and ventilation of the garment is provided in spite of the relative inelasticity and impervious nature of plastic film by cutting a plurality of small slits in parallel rows, the slits being staggered in one row with respect to the slits in adjacent rows. In this way the plastic material is allowed to deform into a plurality of diamond shaped openings which at one and the same time provide both flexibility and ventilation to a plastic garment. The rows of slits are confined, in one embodiment, to the inseams and abdominal areas of the garment. This configuration leaves the knee, frontal thigh, and seat areas impervious to water and thus protect the wearer at those areas in which the outer garments are most likely to become wet, while at the same time providing both ventilation and stretch in the groin and abdominal areas to allow the garment to conform itself to the shape of the wearers anatomy and keep the wearer comfortable. In another embodiment, slits are also provided in the outer leg seam area to give even more stretch capacity and increase the size coverage of the garment. |
