Great Customer Service!
First of all, READ THE SIZE CHART! The medium runs smaller than any other jacket I have worn, and I am 5'10" and 170 lbs (also male if that helps anyone). Very snug. I was able to receive a replacement in a large within 3 days of them receiving the original jacket. The replacement fits perfectly. Extremely pleased with the look and feel of the jacket, the colors POP and it is very comfortable. There was a small defect, a detached button, which I alerted their customer service team to, and they were quick to offer a replacement. 10/10, Mokuyobi cares about their customers.
