Please help me to decide which new sleeping bag to buy. I'm female, 5'8", 145lbs ish. I want a 20 degree down bag. I have a Rainbow tarptent and have a Prolite pad (R 2.8, although I'm considering a Neoair Allseason (R 4.9). (Xlite looks interesting but I want to see more reviews on it). I sleep cold. Main use would be the Sierras in July/August/Sept.
I'm looking at a WM Ultralight 6' bag, which has 16oz fill, wt 1 lb 14oz. The FF bag is women specific (Egret), 5'9", 17.1oz fill, wt 1 lb 15oz. I'm sure I could ask for fill to be added to either. Any opinions on these 2 bags?
I currently have an old Phantom 15 women's long, rated to 15 degrees, 2 lbs, and was chilly in that recently (35 degree night). Overall setup was different tho - I had a Fly Creek tent, and Exped Syn7 mat. Mat was leaky - but the chill was coming onto my back (side sleeper) not up from the ground, alleviated by using my down jacket over my back in the bag.
