This is my first shirt from this company. This shirt has a more slim or contoured fit, which is super if you're perfectly lean. I checked out their sizing on their website and ordered accordingly. I typically wear a Large shirt, but due to the contoured fit of this shirt, I opted for the XL. I'm glad I did, because I believe the fit is much better for me. I think a Large would be too tight with sleeves too short. I'm impressed with the weight and feel of the fabric. The fabric is soft and durable, and it feels like it should last. Many shirts these days are really thin with a cheap feel, but this shirt is not that way. If you order this shirt, I think you will like it. I would however recommend that you get your measurements before you order or make your decision on the size. Overall I'm satisfied with my purchase, and hope to buy more from this company.
