I have never tried drying clothes in a sleeping bag and I thought that it would only make things wet next to you. Lets say if you are in winter and with the temp is cold how does your body make enough heat to dry them? I was just wondering and want to hear any input you may have. I always carried an extra set of clothing if I ever got them wet and dried them a.s.a.p. when I could. So far I have yet had to sleep with my wet clothes.
