Gabriela from Gracie Barra HQ responded promptly providing multiple solutions. Because the gi was purchased using GB Irvine's POS, and not through graciebarrawear.com, they are unable to process a partial refund to reimburse me for taking them in for repair. They suggested that they can take the pants in for repair for me! And if that didn't work, they can also reimburse you in the form of store credit.
Since I just wanted a gi that "works", I opted to get the pants repaired. They quickly sent a shipping label and I dropped off the package. In less than a week, I got my gi pants back with the patch properly sewn on. I am very glad that Gracie Barra HQ took responsibility, even though Storm Kimonos made the gi, and made things right. Knowing this, I wouldn't mind making another purchase from Gracie Barra HQ.

Same gi new issue. Small GB patch on front of gi is coming off due to poor stitching. I only wear this gi every other week and have only own it for less than 6 months. I have 3 GB gi's in my rotation. This is the only gi giving me problems. :(
