This is a domestically produced semi-dry wetsuit meticulously crafted with attention to sewing, specifications, and details. The sponge is based on the highest grade DT sponge from National Rubber Co., Ltd., Japan's largest manufacturer, which is also used by famous overseas and domestic brands. For the outer jersey on the side gussets, crotch gussets, buttocks, and back of the knees, we use super stretch jersey (relaxation jersey) jointly developed with a renowned Japanese textile company, offering excellent texture and elasticity. The suit's brushed lining uses one of Japan's leading highest-grade fleeces, known for its quick-drying properties, mobility, heat retention, and cost-effectiveness. For enhanced comfort during surfing, this semi-dry wetsuit comes standard with an inner neck. By equipping the inner neck, we have achieved improved heat retention by preventing water entry, which was a common issue with traditional designs. We are committed to producing this wetsuit with meticulous attention to detail to ensure customer satisfaction. #surfing #wetsuit #semidrysuit #fullsuit #longjohn #backzip #nonzip #chestzip #longchestop #airflameboost ML Size Details 1 Height: 172 2 Weight: 62 3 Neck Circumference: 36 4 Shoulder Width: 44 5 Upper Chest Circumference: 92 6 Waist Circumference: 72 7 Hip Circumference: 88 8 Back Length: 67 9 Sleeve Length: 75 10 Bicep Circumference: 28 11 Elbow Circumference: 24 12 Forearm Circumference: 26 13 Wrist Circumference: 16 14 Inseam: 70 15 Knee Circumference: 31 16 Calf Circumference: 34 17 Ankle Circumference: 21 (Notes) 1.
