Finally weighed it now that I had to sew the mesh on vs just tape. 10.6 oz (298g) for LDPE, tape, noseeum mesh, 5 short shockcord tieout loops, and 7 short Triptease guylines. Doesn't include door closure, stakes, the long guyline for the pole or the "storm door" I have yet to make, but it should still come in under a pound for total weight.
I didn't put the shockcord at all the tieout points, just the 4 corners and the middle of the 8' back. That's to reduce stress during windy conditions or so I hope since I'm going to the Wind River Range. The plan is to start with the guylines to get the most headroom. If a storm's coming in, I'll re-stake using just the shockcord loops. If it looks really bad, I'll just stake it to the ground using all the tieout points and put up the storm door if needed since I'm not using a bivy.
