After seeing a review of a open front watch coat from Tentsmiths on youtube, I checked out their website and found an 8X8 oilskin trail tarp. I brought it and a closed front watch coat out to run some test on expedient shelter setup as I plan to use these two items on 2 to 3 expeditions in southern Indiana and Ohio this year.
The tarp and watchcoat fold up considerably small for what they are, fit well in the Duluth Scout pack leaving room to spare with the rest of my kit, and are pretty darn light for traditional gear.
Size reference with the pack. I only used these "scrap" pieces of cordage that are in various spots in the scout kit.
