Same full-strength grid diffusion the whites give you, but in black, which is what you want when a big frame overhead would otherwise spray white spill onto everything around it. Full Grid Silent Black softens the light passing through while the black face keeps stray bounce off the walls, and the silent build means the boom op stays friendly when the wind kicks up. LA Rag House sews these in the USA in sizes from the 4x4 slip-on through the 20x20. A rag that earns its spot on the truck.
