“The quality of this shirt is exactly what you’d expect from Roark. Unfortunately the sizing seems to be a bit off on this one. I prefer a large shirt in almost every instance but this ‘large’ thermal fits like a slim medium. I’m sure the material will stretch with age, but putting on this shirt is reminiscent of a wet suit application. I may order a size up, because again, this thermal is built very nicely…just size up.”
