Jiu Jitsu Gis

I am in the market for a new BJJ gi. I’m not picky at all, weave, patches, bells and whistles, etc… are not important to me. The only issue is that I am 6’1’', 310lbs with 21" biceps. Does anyone know where I can find a gi that will fit me? I have an A8 judo gi currently which I can (kinda) get into but it still is a little on the snug side. Any advice is appreciated.

did you say A8?
Im like a 4.5 or a 5 and in some of the older gis even smaller.

I asked my friend He is 63 325 and he says he’s done well with Gorilla gear silverback Gi.
