Mine is a women's long, 76x29 overall specs, black bottom, kingfisher blue top, 3/4 zipper which is very very pesky, always catches on the draft tube (apparently well known for this issue), not sure of year, but 2006 or earlier.
It for sure has areas of very depleted fill. It needs a wash. Its been used on many many trips, both backpacking and car camping. Never got wet but has been compressed and uncompressed a lot. Stored hanging in a closet. But I want something different. Its amazing how frustrating that zipper can be...
Re what to do at night - The Syn7 has already been returned - bad valve. The night I was cold, I was wearing hat, fleece sleep sox, cap 3 long undies and top, R1 top, and put my MB down inner jacket around my back where it was cold feeling. Did the hot chocolate. Didnt do jumping jacks pre-bedtime. Didnt tend to the 2am call of nature, which was probably a mistake. It was a cold night but not windy (drafty) and anyway I was in a Fly Creek with high bathtub wall. Ive been at a colder temp, at 10,000 ft, where we had frost on our packs in the morning and ice in our water bottles, and i was fine, but there were three of us in a BD Skylight, so it was pretty warm in there.
Sorry, rambling. I think a women's speciifc bag is interesting.
Thanks everyone for a great discussion - please continue!
