◇ O'Neill Wetsuit Genuine Product ◇ Semi-dry 5x3mm WFWEC-107A5 ◇ Size MLB. According to the manufacturer's size chart: Height 170cm, Weight 70kg, Neck circumference 38cm, Upper chest circumference 94cm, Chest circumference 90.5cm, Waist circumference 80cm, Hip circumference 94cm. The numerical values are the central sizes as a guide. Since it uses highly elastic material, there is a variation of approximately 2-5cm around the stated values. ◇ Purchased new in December and used twice, but I am selling it because the size did not fit. I wore it on a very cold day without an inner layer, and it was so warm it was almost hot. Please understand that there may be a slight amount of wax residue. *As this is a used item, please understand that there are no claims or returns.
