I'm not going to go into tons of detail, or get into a tussle about what someone else sleeps in, anymore.
I'm just going to add to this thread as far as synthetics go.
I just spent the weekend working with a lot of the Kifaru Climashield equipment. God knows, I've been highly skeptical of this stuff and have said so all along.
Frankly, it blows the doors off the W-stuff. The shell material is actually advanced, the cut is par excellance, the draft collars, cordage, zippers, and overall fit & finish are what has been lacking in a myriad of offerings. We had guys in 0 degree bags doing flawlessly at -10. I had worn climashield material with a 40 degree fill-rating and and was impervious to -10, also.
Weight-wise, they are on par with the Micropuff pieces. Honestly, I'm sold. Hands down, I'll have a standard base bag and a set of the clothes this year. I've criticized them for lots of designs and lots of aspects that I didn't like. The way they are approaching the use of this insuation is dead-nuts useful to hikers and hunters.
