Based off of the other pictures that I've seen on the Supreme website, I can infer that it's fairly cheapish and adequate quality (maybe GG in comparison) based off of two things.
1. The lacing pattern in the modified trap is different than that of HOHs and PPs. The higher quality lacing patterns involve the spiral-type of lace making up most of the web with another lace holding the other down. This one seems to be laced Ichiro style, also seen on lower end Rawlings gloves.
2. Another picture that I've seen shows "Zero Shock" padding. This is the padding used inside Player Preferred gloves. Player Preferreds aren't too great.
Just my observations. I could be wrong, but the two aforementioned aspects hint the quality is parallel to the $60 range stuff
