The suit fits me perfectly in size L (172cm, 64kg). I really like the neck seal as it completely stops the flushing of water I get with a back-zip . Getting into the suit took a little getting used to, but after the first try putting it on, it was easy. I only have 13 dives on it so far and only in summer Ishigaki water (28-29度). One negative point is that a small loop of the external stitching is already coming undone in the crotch area. The internal tape is fine but I need to keep an eye on that area. Excellent value (good コスパ).
