I get compliments on it all the time. New out of bag the gi pants look big but after a couple washes its perfect. My coaches all loved it and two of them actually bought it after they saw me wearing it.

I prefer gis that aren't loud. The fit is perfect and its build and quality is better than all of my training partner's gis.

I've been training for almost 30 years now. The core gi is my favorite, hands down. I bought 5 over the last 2 years all have held up and look good. The royal blue is my favorite, it pops!
