It's not tissue paper thin. Not "glossy" at all. 8.69 yards weighed in at 23 oz so heavier that silnylon should be. prolly coated ripstop nylon of some sort. Good find none the less. so the elusive Walmart silnylon is still out there...

This will likely be some good stuff bags. Anyone have a better design than the thru-hiker instructions?

Thanks for all the comments.
