Thanks for your feedback.
Yes, I too agree that it's snug, more so than the prototype #1 version pictured here:
After finding the supplies at the local hardware store and in an interest of streamlining the production of the tube tent body (now maybe even quicker thanks to the advice of Jim about the 3M guy outs), I went with the simpler more snug design, but so far it's okay for me.
I have had a chance to test it in a deluge, and it has kept me dry. The mosquitoes aren't out yet, but hopefully they too will be effectively repelled. The reason I went with more expensive material on the doors is that I hope to continue to use this design for fastpacking and as the tent body gets worn beyond repair, I can continue to reuse the doors from the previous tent while easily replacing the body.
Durability will get a good test this June with a near 1000-mile fastpack. I've made a couple back-up bodies to switch to at mail drop locations as need be and will definitely be carrying repair tape.
As for the pack, here are some pics of it in action in 2009:
more specifically the flikr album:
It's evolved over the years, but essentially the same old $1/yd white mesh. No signs of serious wear and tear after several hundred rugged miles. Thanks again for the feedback.
