I recently got the HCK in size 5.
I'm 5'9, 150lbs.
Yeah the gi was huge when I first tried it one, esp the pants.
After the first wash there was noticable shrinkage, though it's still big on me.
I bought the 5 cause I don't like it too short.
Hopefully after a few more washes, it'll be just right.
I was told these things shrink only a quarter of an inch during each hot water wash/dryer session.
If I remember, I'll let you guys know how much it totally shrank in a few months, since i alternate
gi's during training.
