After reading reviews that these shirts are slim fight I went one size up and it fits perfect. These are awesome shirts for the price, I just wish they had more color options.
These are the shirts I have been looking for! I would be considered an athletic build at 6'1", 215 lbs. and I don't like to wear shirts that are too tight, but also don't look like ponchos. I purchased an XL to try the fit, then promptly purchased a couple other colors. This has a very classic design, a slightly elastic feel, and very comfortable. It's inexpensive, classic, and comfortable.
I was very impressed with the quality of the fabric and construction. It is far superior to a similar shirt I have bought many colors of at Nordstrom. What impressed me even more is when I washed it today and it washed up FAR superior to the Nordstrom version, for about 60% the price... this is a BEST BUY in my book. If you are concerned about the sizing, I would go a size up,,, it runs a touch on the small side, though I would say standard for a "slim" fit. I'm 5'10" and 155lbs... bought a small. I like things a hair on the small side, not baggy.
