Summary: I bought this bag for the Colorado Trail last summer and no matter which way I slept, I could not stay warm, even though I'm normally a warm sleeper. The baffles are vertical and enabled the down to shift terribly.
Summary: I used this in a Hennessy hammock with a Hammockgear Incubator 20 degree down underquilt a couple weeks ago when the temp dropped to 12 degrees and i was pretty warm. Granted I was wearing Goosefeet down socks and a Rab Microlight down jacket. Pretty satisfied with it.
Summary: This bag is super light and can be packed very small easily. However, for a women, I don't think it's a 15 degree bag and as I was too cold to sleep at 20 something degree night. But i am always cold so i might need a warmer bag than most of other people for the cold weather.
Summary: We were looking to fill a gap between our winter bags(Marmot Couloir, 5 degree & REI, womans Sub Kilo Plus, 0 degree) and summer bags (Mt. Hardware; Phantom 32’s. A late fall-early spring bag, the Marmot Plasma 15 looked like it would fit the bill. So we bought two, regular length.
