They are the same fabric. Duvetyne — also spelled duvetyn and duvetine — is a black cotton twill with a brushed nap that absorbs light. The lighter weights, roughly 8 to 12 ounces, are called duvetyne; the 16 ounce weight is called commando cloth. The rule that settles the choice: if a light source sits behind the fabric, use 16oz. Weight is what stops light bleeding through.
Why the names cause confusion
Two names for one cloth, three spellings for one of those names, and no industry body enforcing any of it. Suppliers use the terms loosely and inconsistently, which is why the same panel can appear on two sites under two names at two prices.
Once you know that weight is the only variable that matters, the naming stops being a problem. Ask for a weight, not a name.
What the nap actually does
The cloth is a cotton twill that has been brushed to raise a short, dense nap. That raised surface scatters incident light in every direction instead of reflecting it back toward the camera or the audience.
The difference is obvious the moment you compare it with ordinary black cloth under a lamp. Plain black fabric picks up a sheen along any curve and photographs as dark grey. Duvetyne reads as an actual hole in the frame.
12oz or 16oz
| 12oz duvetyne | 16oz commando cloth | |
|---|---|---|
| Opacity | Good against front light | Effectively opaque |
| Light behind the panel | Will bleed | Holds |
| Weight to rig | Easier to carry and hang | Heavier; needs more support |
| Packs down | Smaller | Bulkier |
| Best for | Touring, trade shows, frequent strikes | Permanent masking, stage legs, blackout |
How to choose in practice
Choose 16oz for stage legs and borders, backstage blackout, permanent studio masking, cyc surrounds, and any panel with a source on the far side.
Choose 12oz for touring sets that get struck nightly, trade show booths, location work where weight in the truck matters, and flags and floppies where the panel is lit from the front only.
If you cannot answer the question “is anything lit behind this?” with confidence, buy the heavier one. The failure mode of too light is visible on camera; the failure mode of too heavy is a sore back.
Practical notes
- Nap has a direction. Hang panels consistently or they will read at slightly different densities under the same light.
- Cotton shrinks. Allow for it if you are hemming to an exact finished dimension.
- It sheds when cut. Expect loose fiber from the nap on the first handling.
- It is not a blackout curtain. It absorbs light rather than reflecting it. For total light blocking across an opening, you want opaque cloth plus overlap at every joint.
A note on flame ratings
Most venues with a fire inspection require certification for the specific lot of fabric, not a general statement about the material type. Do not assume a rating from the fabric name, and do not accept one without paperwork that covers the roll you are buying. If your venue requires certification, ask before ordering.
Frequently asked
Is duvetyne the same as velour? No. Velour has a much longer pile and a richer look, and is usually chosen for front-of-house drapes. Duvetyne is a working fabric for masking.
Can I wash it? Washing raises the nap unevenly and can affect any applied treatment. Spot clean where possible.
What width does it come in? Commonly 54 to 55 inches.
