The truth is, these fabrics do breathe, albeit not approximately in addition to, say, a base layer shirt or maybe the light-weight shell fabrics you see on most sleeping luggage these days. So whenever you perspire during the night, this perspiration will go through the inner cloth, into and ideally in the insulation, and thru the outer cloth, the place it is going to evaporate.
usually that has a foundation layer of merino wool in addition.

And which has undoubtedly happened, however even then the humidity did not enter into my insulation and I didn’t suffer evaporative cooling. But, I concur There's a fantastic bit about the complete issue that is definitely subjective. It might be simple plenty of to put it to the scientific test as far as warmth and loft retention, but I haven't found that. Other than my very own private experiments, with N=1.

The principal outcome of a VBL is halting the transmission of insensible and wise perspiration, i.e. sweat, absent out of your overall body, proficiently developing a microclimate between the VBL and your body.
