I've been looking for a solution since my wife bought this for our fair weather walk-ins. Cheap at $69, roomy for 2, light at 2# 10oz, and free-standing. If it could take a little rain and wind it might cover 95% of my outdoor nights.
This design has been sold under REI, Sierra Designs, Walrus, and another I can't remember. At some point a low coverage fly was offered, but no longer. Some people have MYOG flys with better coverage. All leads have been short notes on blogs, no pictures, and eventually dead-ends.
Any suggestions? I don't think I can come up with a pattern from scratch.
