Are Merino cycling boxers/cycling pants worth the cost?
Those merino boxers you linked to aren't cycling nicks, they're just
  underwear. You'd still have to wear somethign over the top of them. If
  you're spending any time in the saddle I'd suggest a proper pair of
  cycling nicks - with a chamois. That said, I got some cheap merino
  thermals at Aldi, and they're great. Warm in the wet, but not sweaty
  like lycra. You can even machine wash them.


I accept this comment, to get this question away from unanswered list. I will remove this if the original commenter makes the comment as answer. I think the comment/answer is good because it cuts the marketing facade into issues such as proper pair of cycling nicks (with a chamois) and machine-washing -- and needless to get some XYZ -branded merino [wf]-ools, even discounters offer proper ones.
