Size is XXS. Purchase price: ¥24,200 (tax included) Purchased this year from mic21. Unused. High insulation, heat retention, and waterproof functions are achieved by applying a heat-reflective coating to 1mm wetsuit fabric. Also, the collar and line parts use "H・C" with highly elastic titanium processing, an inner with high heat retention. 【Approximate Sizes】 ◆XXS size: Height 140-150cm / Chest 74-80cm / Waist 56-64cm ◆XS size: Height 145-155cm / Chest 77-84cm / Waist 58-66cm ◆S size: Height 150-160cm / Chest 80-86cm / Waist 64-70cm ◆M size: Height 160-170cm / Chest 84-91cm / Waist 68-75cm ※Unisex. For reference, I am 167cm and 52kg, but I became XXS when I tried it on at the time of purchase. I don't think you need to worry too much about the height size indication.
