I just noticed this—-Smartwool base layer for $83 instead of $110 ((lots of colors).

Their own REI brand merino is even less—-$55.89. It is slightly thinner. This one get faulted by a few reviews for having a tight neck. I bought one and it is fine on me, but I do have a small neck. I do find the shoulders a bit narrow, and the body length is quite long on me (5’2”). If you are taller, like 5’6” or more, it should be fine.
The men’s selection includes some patterns like this, in quarter-zip or crewneck.
