Alpha 60 Pants/Leggings

I do realize what sub I'm in, and that most of you ul folks sleep in your hiking clothes. I'm just not quite there yet and hoping that you can provide a little wisdom here... Do you wear Alpha directly on your skin?

I picked up a pair of senchi alpha 60 leggings (3.4oz) with the intention of wearing them as PJs and for comfy chilling around camp. But they're a bit see through, and an internet search tells me they're made to be worn over a base layer. Except that seems to completely kill the weight savings for me to carry a baselayer + the leggings. Thoughts?

Also what about up top? Are you wearing your alpha hoodies as a base or a mid layer?
