Our Stealth Blackout Curtain was born from trying to go stealth mode (staying in a place not designated for camping) in our van. We used to put window coverings in the front windows, but this seemed to signal to everyone around us that we were sleeping in the van and resulted in getting asked to leave. The Stealth Blackout Curtain allows us to simply close a curtain each night and makes our van look like a parked vehicle, not a camper. The curtain is tailored from heavy duty diamond rip stop fabric to the curves of the van and includes carefully placed magnetic and tie closures to block light from leaving the van, which would ruin stealth mode. This curtain is a must have for anyone planning on urban camping in their van! The curtain simply ties back to stay out of the way when not in use. The curtain also helps tremendously with heat blockage from the front of the van while trying to stay cool in the back.
