Commando and Duvetyne are economical fabrics best suited for masking applications. They come in a variety of weights including 8oz, 12oz and 16oz. Generally, the term duvetyne is used to refer to a lighter weight fabric, while commando designates a heavier weight. Both terms are largely interchangeable and neither one is specific to any particular fabric.

Duvetyne/Commando is a good choice for limited, short term use, curtains or where a more disposable type product is desired. It has good light blocking properties but is not particularly durable and is highly susceptible to water/moisture damage. All versions come in black and some versions are available in a few colors. For a wider color selection there is usually a minimum yardage requirement.

An exception to the above is the TV/Film industry where a very heavy weight version is commonly used. It is still referred to as duvetyne, in spite of its heavy weight. Curtains are primarily portable – moved from location to location. While heavy weight duvetyne is commonly utilized out of tradition, fabrics such as Prism and Encore often offer better overall performance at a lower price.
