I purchased this about 10 years ago for scuba diving. I've used it about twice. The size is women's M. As you can see in the photos, there are zippers on the sleeves and ankles for easy on and off. There are almost no scratches and it's clean. Measuring the cuff with a ruler, it's about 5mm thick. Scuba diving Wetsuit SAS Full suit
