It is very important that garments be sized correctly. Improperly sized garments can raise the level of contaminants and cause safety concerns.

Cleanroom garments must have these basic characteristics:

• A minimum of seams. The seams must firmly envelop the edge of the material.
• Be loose fitting to eliminate abrasion
• Absence of pockets, belts, and pleated or tucked areas.
• Tight fabric weaves to minimize the passage of dust.
• Fabric must reduce static electricity generation and still remain nonlinting.
• Garments should cover as much of the person as possible, especially around the neck area.
