Outer: Skin (Rubber) Inner: Skin (Rubber) Both sides are made of rubber material, so water will not soak in, keeping you warm. The skin material is soft, allowing for free movement. It also becomes softer over the years. The rubber does not stretch. Putting it on is smooth if you put water in it before wearing. Used for about 2 years. Height: 162 cm (up to around 170 cm is possible) Body type: Average (neither thin nor fat) Weight: 55 kg Normally, the knees get scratched, but since I wore knee pads, there are no scratches on the knees. Excellent. Since it's rubber material, it stretches and shrinks, so people of similar height can wear it. The stomach area is also long. It comes up to around the chest. If it fits, you can wear it as is, but if it's loose, wear thick fin socks. My name is written on the inside of the stomach. The silver color is slightly peeled off due to pulling it up from the waist inside. It has been stored folded, but there are no noticeable creases. In short, For divers who get cold easily, the ultimate solution is a 6mm wetsuit. I used to dive year-round, so this is fine for all seasons. For hot summer days, I recommend wearing a rash guard on top and this 6mm wetsuit on the bottom. It's comfortable. This is a used item, so please refrain from purchasing if you are concerned. If the height fits, you're lucky. I am also selling the top separately, so please take a look. I am considering a set discount, so please consult with me. #scubadiving #6mmwetsuit #wetsuit
