No, sorry.  But if you're looking for a cold-weather long underwear type baselayer, you might try fleece pants.  I wear them under my waders for winter steelhead fishing and they work great.  I wear a light pair of zip-off type fishing pants over them, and it's very comfortable.  The fleece is good in case you get wet; not that that ever happens to me while wading in an icy steelhead stream...  Also works well under raingear on a cold fall or spring day in a canoe.  I don't even own any long underwear anymore.
