Would it really, considering that the dew level could well be someplace throughout the sleeping bag’s insulation? I'd surmise the vapor would ‘want’ to travel right in the clothing system and outward along the temperature and humidity gradients to some (dew)place uncovered deep in the sleeping bag. regretably for Mr. Vapor on the other hand, the outward certain drinking water vapor would speed correct in to a proverbial brick wall when it attained the sleeping bag’s water resistant interior shell. Probably then a VBL-accommodate would not be required in any way–just an outer shell about the puffy that was breathable nevertheless markedly ‘watertight’, e.

After i get as well scorching, I sweat, VB or no VB. (naturally, VBs heat me up, so I would sweat in a decreased ambient temp).
