they also have an SLC or something, a higher end version of this
Just an FYI I wore this yesterday at the ibjjf chicago open with no issues at all. I saw maybe 3 others that wore them as well. So they will be allowed by ibjjf. Also I just as a note to how much I like the gi, I ended up weighing in at nearly 10 pounds below my weight class but I wore the gi anyways as it has become one of favs.
