Tried Search function, but didn't come up with anything.
Here's what I'm looking for, hoping someone here might know of just the thing..

Midweight thermal top and bottom. Must fit a tall and lanky sumbich (me).

Material: NOT poly. Much prefer Merino wool or similar natural blend. Poly, no matter treated or not, always ends up stinking, IME.

Top: long sleeved with quarter zip or partial button down. No crew necks for me. Arms must be generously long. Collar is preferred, but not mandatory.
Bottom: piss flap, and again must be long in leg.

Any ideas?
