I had sort of taken it as gospel that you want to have dry separate clothes for sleeping – for a variety of reasons partly avoiding getting cold due to moisture in whatever I'm wearing around camp, partly for bag longevity (keeping extra dirt/moisture), etc…
However, in the interest of reducing weight, and in some cases extending bag temperatures, it seems like a lot of folks dispense with separate clothes for sleeping and sleep with some or all of their regular gear on (temperature dependent…).
So how many people keep a separate set of clothes to sleep in, and if so, what do people use? I've mostly been sleeping in cooler weather in some form of light base layer top and bottom…
