After trying tarp poles on my HG Dyneema (Cuben Fiber) Tarp with doors, I still had fear of my bridge poles popping through the Dyneema especially on exit. I wanted to try out a design that might minimize this problem. I used RBTR Membrane Silpoly PU4000 from their outlet as a trial. My goals where to create a tarp that was light, provided adequate coverage on the sides and ends (doors), and most importantly moved with the bridge to prevent damage (think overcover combined with a tarp). I decided on a 10 ft Square Tarp Build Finished 120” x 90”. This is simple to cut and sew. I used extra fabric to make a single tarp skin.
Here is a graphic of the design as well as details on the build and project.
