Thank you for viewing. The size is not indicated, so it's not clear. Length: Approximately 62cm, Width: Approximately 44cm These are amateur measurements, so there may be some errors. I am not very familiar with wetsuits, so I don't know the thickness in millimeters. There are some areas with minor scuffs. This is a used item, so there may be oversights. I have other items for sale, so please take a look if you'd like. Thank you.
