I've read about the importance of having a set of dry clothes and dry bag to sleep in, and I understand about minimal clothing and layering and changing back into wet clothes for the next day. However, what do folks do when their base layer is also wet and it is cold enough that you need it? The risk is transferring that moisture to your down bag. My base is smart wool so it has kept me warm when wet. I guess the question is for an early March start of a NOBO is it smart to carry a dry micro weight base for sleeping. Is it worth the weight penalty for an item which can be sent home in April or May? Not sure I could afford a "second" base layer. Just asking. Thanks.
