so many sleeping bags!

I have a Kifaru  0 degree slick bag.  Nice bag.  Not worth the money and no were close to a 0 degree bag.  And if you are over 5'6" order the tall.  Much better options on the market as mentioned on here.

  Do you have experience with other bags to be able to state that the bag isnt actually 0 deg?  I guess Im asking if you consistently find the bags to be true to ratings or are always cold.  My wife gets cold in my 20 deg bag when its 40.  Im usually just in boxers with it zipped open and Im half out of the bag at 40.  Ive taken that bag out in -5.  So if she would come on her and state _____ bag temp ratings arent close ... it really isnt true to the bag but to her personally.

Yes, I have a lot of experience.  There were times I was spending 200 nights or more a year in multiple weather conditons.  I would have a problem calling my bag a 20 degree bag.
My Kifaru Woobie is warmer.

I use
Enlightened Eqipment quilt 20* ... 18 ounces
Or
North Face cats meow 20* 2lbs 3oz

When it's really cold I just keep my clothes on and wear my Kelvin puffy and a beanie! No need to carry a zero degree bag that is double te wieght when you already have merino layers and warm clothes that will take the place of a heavier bag!

I have a Marmot Goretex down that I bought in about 1993.  It has been awesome and held up great, I've been in it down to -20 wearing everything I had and a bivy sack.

Check out the Montbell Downhugger. Very spendy, but worth every penny. I went with the 2 and long. As light as quilts and much more comfy, being a stretch bag.
