Why a large orange plastic bag? It’s actually one of the most valuable items on the list. Crawling into the bag helps keep you warm and dry. The orange colour is also highly visible and helps attract attention, particularly from the air.
its your call what to bring … but in several rescues over the years here NSR has stated outright that they wished that the hiker/snowboarder/snowshoer/etc … brought and displayed stand out colours in rescues …
they know a thing or two about it i should think, being BCs busiest SAR rescuing all those city slickers ;)
"The three hikers were all dressed in black, green and blue, and were very difficult to see against the tree canopy," he said. "We knew it was legitimate; we just didn't know exactly where they were, and in that terrain 100 metres means everything."

Although they were well equipped, the hikers in this case wore colours that were impossible to see from the helicopter, said Jones. He advised hikers to always bring bright clothing or something else that's highly visible, like a bright orange garbage bag, and to clear the forest canopy when waiting for rescuers.
