I have some and it is good quality. One thing to pay attention to is the material content. Even though it says merino, it's usually 50% merino - 50% polyester.
It's more durable than all merino.
I like the 100% merino stuff better. It seems to handle moisture better, and feels more comfortable against my skin.
If this is going to be worn as a 2nd layer, it may not make a difference.
