I do like the look of Ulrich's I do...I think Jess is at the top of her game though, just based on the two examples I've seen and the gushing reviews from the two knight brothers of mine who own them. Since I'm not sure where I'll ultimately reside, I'll stick with my Icefalcon gambeson for now (which, despite its thickness, is not a trial to wear, no overheating at all- but I did sweat quite a bit as one will).
Both Jess and badassgarb do custom work though so I'd go there before I went with anyone else. Icefalcon's stuff is off the rack so if you're a weird body type or outside of the sizes offered you'll not be happy.
