I've had a Sierra Trading Post MyUpdates subscription set for 'merino' since May. Ideally, I want to try a crew neck top, long sleeves, tall with a small percentage nylon or something for shape retention. Best price I've seen was $60 but it wasn't a tall so I'm still looking. If you see anything I'd appreciate a heads-up if you think of it. ;)

I did snag a doufold cotton merino blend from Fleet Farm a while back. I'm wearing it right now. Even though it has cotton next to the skin I find it a little itchy but tolerably so. It was under $20 retail so perhaps the merino isn't the best quality?

This may sound weird but that's never stopped me before so...
I can wear a next to the skin cotton top for a week on a trip easy. Anything poly, you name it, I can't stand wearing next to the skin for more than a day or two. The best description of why is it simply makes my skin hurt to the point I have to put a t-shirt under it and my arms are still unhappy after day three.

If anyone with half a clue what I'm talking about with some merino experience can comment I'd appreciate it. I can live with a mid forearm sleeve length and sometimes that's a plus but I don't need any more $60 thermal underwear for sledding and ice skating. I have numerous weights and enough for a full load in the washer already.
