I purchased two shirts that were both too small so I Exchanged one and applied for a refund for the other. To make matters more complicated I needed the exchanged shirt quickly as I was going on vacation and wanted to take it along. The process was seamless, quick and very pleasant. My shirt was actually FedEx'd to my home once it arrived stateside and my refund was promptly credited back to my card.. Quick note my measurements recommended a small/medium but the large was the best fit . I am 5-10 and 200lbs of average build. A great buying experience with superb customer service. A rare commodity these days. :-)
