The 20 x 20' Sunbounce Wind-Killer Screen is an unparalleled location tool designed to minimize the ill effects of wind on photo, film or video shoots, allowing you to shoot when and where you want to. Especially useful for wind-sensitive Steadicam work, the transparent material fits a lightweight, collapsible Sunbounce frame (not included) and can be hand-held to cut 75% of the wind, leaving only a moderate breeze.
