I purchased a set of Kerry Covers (sold under the label "Uncuttable") for my ASH26E from Wings&Wheels a few months ago. They are as you describe, and came in about a week. The bag they came with was big andreally awkward in my trailer, so I now store the covers in two duffel bags of 65L each (fit is a bit tight - 75L would be a better size) that are placed on each side of the tail boom ahead of the fin for travel.
My only complaint is I had to assemble the bungees for the covers (about 12-14, and there is a trick to it that is not described anywhere. I think the bungees should have come ready to use; after all, they know exactly what aircraft the covers are for, so why make the pilot hassle with them?
