I put in an order this morning. MF, not GWS. I went for the 5 degree Sequoia semi-rectangular bag. Its probably not what I'd get the most use from, but I have decent bags for down to about 30-35 degrees, I don't have anything in a backpacking weight for colder weather, so this hits the biggest gap in my equipment.
Thanks for all the input, guys.
MF or GWS you will like WM!
I have two of their bags and I couldn't be more pleased.
