Yeti under WBBB & TQ over all. Then just "ignore" the clammy feeling???
Would the driducks work differently if put on "inside-out" ?
Real curious about this thread.
Driducks breathes too much. It will slow vapor transfer, but it is not a VB. You can probably skip the liner gloves as I don't believe there would be any thin enough to fit beneath a pair of VB gloves.
The clammy feeling is not pervasive with a good VB set up. You'll notice it from time to time, but it is not the same sort of "cold clammy" that most of us are accustomed to.
Some folks just use a VB bag liner that can be found at campmor.com in a reflective
type. I've found that the vapor tend to pool more in these than with VB clothing.
If you have a silnylon Packa, you've already got a VB top. Just close all of the vents.
Personally, I'm looking for a lightweight sauna suit. Some might argue that it is single use; however, in SEVERELY cold weather, you could still keep the VB layers on through your hike and it will boost the insulation of your garments significantly. (Your head and your hands can still regulate heat at those temps.) Even if just used for sleeping, it "could" offset the weight in a couple of ways. The most obvious is that it can reduce your need for more insulation to the tune of about 20° F. The not so obvious weight savings would be that your TQ and UQ will not have gained the weight from the vapor being trapped inside. (This can add up to POUNDS saved.)
Finally, a VB layer is the best way to prevent frostbite. If your feet are in a VB sock surrounded by sealed in warm perspiration, they can't freeze.
Again, if you're out in temps above 20 F, the benefits are there but not as large. The colder it gets, the more benefit there is.
