The website is http://www.navyrackpacks.com. These blackout curtains hang inside the existing ones in Navy racks on ships to help with sleep, as berthing areas aren't the best for light and noise. They have extra pockets for storage, and last name is embroidered for free. The business is woman-created and owned: her name is Pat Neleski, and she will answer all questions :) 855-722-5722 or email email@example.com. Sailors love these.
