I've been on a search for long sleeping pants to use on multi-day hikes. Ideally, these would be warm and light. While I might use them underneath my hiking pants if it got really cold, their main use would be something to sleep in on cooler nights. Here is the thing though - I HATE the feel of tights -- form fitting legging-like pants. So, I am looking for something with a loose fit ... sort of a pajama bottom that is made from a material that is suitable for hiking, warm, and lightweight. I can't seem to find a pair that fit the bill. Anyone got something like this to recommend? Thanks!
