By far the most reasonable explanation is a roll with two or more colors of fabric. Spooling fabric is the quickest, safest and most practicable way to package and ship large amounts of material. Six pounds, including the center roll and the box, is totally within reason.

It's been clear to me for a while that bumpers are an area of the competition where two problems are developing for FRC. One is the constant frustration and occasional danger that is caused by teams that come to competition with incomplete or insufficient bumpers. It is often the last thing that young teams consider in build season, and with the goal being to get all teams to pass inspection, I've seen questionable bumpers okayed for play. The other is teams that are using bumpers to gain advantage through materials and construction that augment the original purpose (protection). See this year's sailcloth experiments.

All that is to say I would not be at all surprised if bumpers were standardized, and even increased in size. Three pool noodle height, perhaps? That would also increase protection, as well as the visibility of the (larger) team numbers, both of which would be highly desirable. I'll bet that the light 29" box is also bumper material.
