I love sleeping in down puffy layers. I sleep cold and have found down to be the best for me, as long as the exterior shell is soft and pretty quiet. I need a new pair of pants because I gave my last pair to my son. I think they were Arcteryx but they don’t appear to be made anymore. I see the ones from Stone Glacier and Kuiu, but I’m not sure if those are suitable as a base layer and or soft enough for sleeping. I don’t want a hard and loud outer shell designed to be an exterior layer. Suggestions? Packable and light are a must too.
