Loving the Mykonos color. I really like the weight and fabric of the shirt. It's a blend, but it's still acting like merino in my experience. I used to be a purist - 100% merino only, but I've come over to the blend side for the better feel, easier maintenance, and I think they're less interesting to moths.
Personally, I wish this was more of a long sleeve crew. That's how I want to wear it, so the thumbholes only detract.
Note that this shirt is snugger than some others. After reading reviews, I bought a M and it's perfect. I wear a S in the SS nuyarn shirts.
