blackcatdownClose. . . Personally I like to keep it simple and lightweight - don't need a zipper (or pocket) on a base layer! Maybe something like the Icebreaker Oasis - the leggings and t-shirt in one drop? There was a recent drop for women's Oasis leggings that I picked up for my wife. If I could get the whole layer top and bottom for $80-90 I'd be a happy camper.
Basically exactly what you're looking for. Request it, it might drop again in the future.
