I used to always wear the standard black military t-shirts that I wore with green/tan/black older BDUs, but these shirts are now my new everyday favorites. Great fit, high quality materials and excellent value for money. The shirts are for the Asian market (China I think) and are one size smaller than what we have here. So if you order a "Medium" size, the item you receive in the mail will be "Large" on the t-shirt tag, but "Large" for Asia will be "Medium" in the US.
