Antarctic Item 056

This item is made of two large pieces of fabric. An orange field meets a black field in what feels like waterproof material. Whatever it is, it is incomplete. At some point the orange area was cut into with pinking shears, reducing its size. The excised segment, which might have provided clues to the item's function, was lost by the time I acquired the remaining fabric. What could this missing section have been? I imagine it was the bottom portion of a high-visibility tent cover which, once the tent was pitched, came into contact with the frosty Antarctic terrain. When the time came to strike the tent, the bottom edge of the cover was encased in layers of ice which had built up over a week of strong gales. The shelter's occupants had no choice but to cut the protective cover free from its mooring, which they did with pinking shears as not to dull their more essential blades. With the tent cover remnant in tow, they continued hurriedly towards their destination ahead of the next impending storm. Or at least that's the way I imagine it.
