Height of 177 cm, weight 80 kg, chest circumference about 100 cm, so I bought Size XL but it was Just fit.
Base fabric is stretchy and coarse Mesh.
Shoulder Protector Fit feeling can be adjusted with Belt in front and back and side part.
Chest Protector is Quantity : 1pc. It's a structure so it's comfortable and it's Size that covers to the bottom of the ribs, not to mention the heart.
Spine Protector reaches the coccyx, but there is no sense to be pushed up even if you sit on a chair while wearing it.
I got lost with other products made by Komine, but the part with shoulder Protector is the point that pushed the purchase.
As long as it is not a very special person, as long as you buy Komine's Size street products, I do not think it is a mistake, but I recommend you try on it beforehand if possible.
