The GDFB stuff is starting out as somewhat blackened, but the black flakes off, so it's getting more metallic as time goes on. You can see that in the photo with both the haubergeon and hauberk, the haubergeon is a little lighter in color since I've used it.
The hauberk comes without the split, so you have to add it yourself.
Latest update-- I finished removing material from the front and back. I hope I didn't take out too much. With it pulling at you, it's hard to hold the front shut (with no lacing or anything) just to see how it's fitting. I'm going to try it on over a gambeson and lace it shut and see how it does. Worst case scenario, I open the back up again and add some material. But I think I have it sized down to 48" now. I'll double check. I just don't think I'll have time this weekend to do any of this yet.
