I remember several years ago a product kinda like this. Except for it had suspenders up at the top. This allowed you to slip your arms out and the blanket would drop out of your way when you stood to shoot. Always wanted one, but never tried it. The thought of trying to get the thing on while standing on a 2x2 platform, 20' in the air, did not appeal to me. Nonetheless, it might be a stretch, but sometimes you got to take risks owning a small business.
