Beautiful Seea Yulex Long Jane wetsuit, 2 mm, I only wear a couple times, nothing wrong with it , there’s a little mark on the knee area from wax, barely noticeable, watch the video. I would say it fits like a S/M. This is some more details about Yulex wetsuits: For cooler waters on beautiful sunny days, the Sydney 2mm natural rubber sleeveless Long Jane will be your new favorite companion. The sleeveless style with long legs provides just the right amount of core warmth and protection for sensitive ribs and knees while feeling lighter and freer than a full suit. A velcro and button shoulder opening makes it easy to slip in and out of, plus darts on the waist mold for a snug and flattering fit. The knees are reinforced with extra padding for durability and comfort while knee paddling. This suit is made out of Yulex, a plant-based replacement for neoprene. It is very stretchy so if you're in between sizes, we recommend sizing down. Questions? Leave a comment below!
