Love this judogi so much I bought the white and the blue.
Perfect fit (183cm / 85kg) with the 4.5. I've put the blue through a dozen wash cycles so far, and it's still vibrant, which isn't always the case with blue judogis. It's a heavy GSM, but considering my previous two lighter judogis were torn to shreds due to repeated abuse, I'm very happy with it.
The pants must be the most comfortable pants I've ever tried, too; a welcome surpirse!
