My son is 6'1 and @ 140 lbs. I need to replace his gi (at least his pants) and am having a very difficult time. His last gi was KI heavyweight, but that was a hand-me down from me when he was smaller. I had him try on a Karate Depot elite size 5 and you could literally fit a whole extra person in with him. I can't see any amount of washing that will shrink the waist down enough without also shrinking the length. Does anyone have experience with any gi made for a tall, thin person?
