I'm considering getting either a Warm Bag or Heater Body Suit and wondering about pros & cons of each. Anyone have any suggestions? I've looked at both online & I can see that each has it's advantages & disadvantages. I like the insulation of the HBS, but don't like the bulk. I like the arm opening system of the WB, but don't know if it will be warm enough. I want to use it in MN at the end of December so it has to be warm enough to handle temps at or below 0. Water repellant fabric is important, but not crucial. I'm not too concerned because most precipitation when I'm using it will be dry snow.
Thanks in advance for the input.
