Must have been some cheap brand to rip that easy. I'd used a piece (Duck brand I believe) for a groundcloth for several trips (some on rocky sites) that held up quite well until I sacrificed it to bundle up 15+ pounds of trash I hauled out.

However, another piece ripped the first time I used it. That may have been Ace brand.

Nonetheless, I can't envision how you're using this, and the head end is not where I'd want to since it's not at all breathable and you'd have significant moisture from your breath there.
