This is a wetsuit (semi-dry) purchased in the US about 5-6 years ago. It is an XCEL COMP X, 4.5/5.5mm, size MS. It fit me perfectly with the following measurements: Height: 170cm Weight: 58kg Chest: 90cm Waist: 79cm The condition of the item is as follows: - After each use, I hand-washed it with tap water and dried it indoors before storing. - There is a cut on the thigh from a fin, but it does not affect usability. - The rubber edge of the hood shows some signs of age-related deterioration, but it does not affect usability. - Also, although not very noticeable visually, the area around the buttocks is thinner than other parts, making it easier for water to seep in. I compensated for this by wearing a warmer inner layer. In my personal opinion, it is fine for winter in Chiba North for shorter periods.
