Oh well, I'll still try to make a repeatable measurement for later. Actually the first thing I want to do is re-bag it in 3-4oz packets so that I don't have an explosion of 16oz like Bob!
I saw your hood threads, they look great. Did you use a pattern I could get to? If not I'll trace a jacket hood onto scrap. I will make one out of my scrap quilt materials, might even make it attachable to the quilt, for a quasi-mummybag.
I don't know what's next, I actually think I'm going to go down in complexity and make a tarp/shelter. Maybe MYOG Cuben gatewood cape? Definitely want a day-hike/nice weather forecast simple shelter to toss in the bag.
