Updated review. My issue is resolved.
Updated review: I did not love the undershirts. They fit and they are as advertised, but too thin for my taste. Also I’m used to cotton and this feels very differently. It’s not for everyone. I requested to get a return label and refund and had not heard back after contacting the company a few times. A week and a half later, they did respond and will process a return. They had a support gap, which I hope is resolved now. Bottom line, the product could be for you, but not for everyone. Their support had a hiccup, it seems resolved now.
