Looking for IHJ-99-IND 6.8oz Chambray Bomber Jacket

[indigo_fades]

Just found out about the IHJ-99 jacket today, and I love it. Couldn't find much info about it online, but found it here on the forum to verify. Saw it on eBay, but only size small was available.
If anyone knows where I could find a size Medium please let me know! Thanks!
