All these shirts are pretty much same quality. I've purchased from several companies. Some have breat pocket which I like for a slightly more casual look. I'm 6"1 180 so large and extra large fit. I'm not into the trend of super fitted tight shirts or short flood style pants. I like classic style. I prefer the extra large for a looser fit with shirt outside pant. The sleeves are 1/4 too long on extra large and I have long arms with that said I wear the xl with jeans and roll up the sleeves. Under a sport jacket I'll wear the size large with sleeves down. By today's standards the large is a perfect fitted fit but I'm older school and like more shoulder room. So I bought 2 of each color in 2 sizes. They are great all season winter and Summer shirts. Love the quality and look of this stretch fabric. Looks very nice not cheap whatsoever. Looks like $100 shirt. Like I mentioned there are several brands out there with very little difference. I bought about 12 shirts total in both sizes and all colors. They go with Jeans , dress slacks or a suite. Classic styling . I even found them in Short sleeve. Will probably never buy another shirt again. Love the black, white, navy blue and Lavender
