Bjj - thickest competition legal collars?

[Matt Crush]

I want something like my old Howard . Who makes a medium weight gi with a legal collar that will make people say 'WTF? '

I have seen some Keiko gis that had seriously stiff collars. That is really the only brand that sticks out to me in a normal gi. The other gis with memorable collars were all double weaves.
