I have never used this item since I purchased it. The size is S. ✳️ This is a one-piece suit with long sleeves and long pants. It is made of high-quality stretch neoprene and has excellent elasticity. There are three types: 2mm jersey lining, 3mm jersey lining, and 5mm fleece lining, and the thickness affects the warmth and mobility. Choose the thickness according to the season, water temperature, and activity. ✳️ 5mm type: Zippers are attached to the wrists and ankles for easier on and off. The inside is made of brushed material, which feels good on the skin and provides excellent warmth. 2mm/3mm type: Made of high-quality stretch neoprene with a jersey lining for excellent elasticity. ✳️ The Y-LINE design on the back distributes the pulling of the suit well, allowing for smoother movement. It has a back zipper, making it easy to put on and take off, and allowing you to enjoy marine sports comfortably. There is a lining on the inside to prevent direct contact with the zipper, which prevents skin chafing.
