Our original and best-selling blue Rising Sun bomber with custom chainstitch detail on chest and back. This is a special limited edition run so we only have a few sizes available! Sizing We recommend measuring a jacket you own (laying flat) and comparing it to our measurements. As a general rule, women's sizes tend to correspond with their US t-shirt size, and we recommend men order one size up from their normal t-shirt size. If you're in between sizes, pay close attention to the armpit measurement and size down if you are unsure, as this jacket is not meant to be oversized.
