I'm 6'4, about 275, with relatively broad shoulders and long arms/torso. I bought a 3x tall and find it matches the roomy side. I like loose shirts in general so I'm keeping them but will try 2X Tall next time. As a general sizing statement, they are larger compared to other brands that sell 3 XLTs. I just bought them and only wore them once but the shirt is comfortable, relatively light but well made (suitable for summer here in Florida) and I think it's a good buy at $10 (got 2 packs for $20 Bought).
