"What has happened to black diamond quality!? It used to be an industry standard, but now is flimsy, cheap and poorly designed. Will never buy another one of their products again!"
"Solid base layer. Runs a bit on the smaller size. Definitely would recommend."
"Fits well, soft, warm. Great shirt. Highly recommend."
