Fantastic shirts - I purchased the Stonemaster and the Sierra. The shirts are well made, constructed of durable fabric, with bright and vibrant colors. Now, regarding sizing: based on another review, which stated that one should size up, do not, absolutely do not, size up when purchasing any of Withernot's shirts. These are the most generously sized shirts I've ever encountered (I wear Brooks Brothers shirts, so, I'm used to a generously cut shirt, but these shirts go beyond.). It is rather nice to encounter a company that doesn't cut corners when manufacturing with regards to sizing. I wear an XL and sized up to an XXL based on the review I read and allowing for shrinkage. The shirts were comically large. Huge. I worked with Patrick at Withernot and exchanged the shirts for an XL. The XL was also too large. Back they went. Patrick exchanged the shirts for a large, and the fit on both shirts is excellent. Overall length of the shirt is good, sleeve length is good, and there is room to move in the shoulders and the torso.
The return process was effortless, and made so by Patrick's fast, efficient, and friendly customer service. Excellent shirts and a fine company to work with.
