My husband needed long sleeved "undershirts".  Searched the web and tried Amazon. Many selections to choose from with Amazon but found the price on these were good, shipping was included, and a name brand. I bought 3 in black.  The shirts washed well and my husband likes them!  They are very comfortable and look good on him!  He normally wears a Large but I purchased Extra Large because of the cotton content. I wash in cold and dry in delicate so shrinkage is usually not an issue but I am glad I did purchase the XL for the comfort factor.  I think the large may have been tight. I'll be purchasing more. I was really impressed with the quick shipment from this seller!
