This is $13.98 at Sam's Club. Merino/synthetic blend. At that price you should get one just to see if it works for you. I use them for cycling, running, etc. Good product. The best part is the rain resistance. If it is drizzling, no need to put on a rain shell. Sam's sells their socks as well.

OMNIWOOL Multi-Sport Hiking

Sam's sells this as well. That would be good under the helmet. For the price, I might have to get some and try it out.
