This is a domestically produced semi-dry wetsuit meticulously crafted with attention to sewing, specifications, and details. The sponge used is based on the highest grade DT sponge from National Rubber Co., Ltd., Japan's leading 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 a super-stretch jersey (relaxation jersey) jointly developed with a renowned Japanese textile company, offering excellent texture and elasticity. The suit's brushed lining utilizes one of Japan's top-grade brushed materials, known for its quick-drying properties, mobility, heat retention, and cost-effectiveness. For enhanced comfort during surfing, this semi-dry suit 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 suit with meticulous attention to detail to ensure customer satisfaction. #surfing #wetsuit #semidrysuit #fullsuit #longjohn #backzip #nonzip #chestzip #longchestop #airflameboost MLB Size Details 1 Height: 174 2 Weight: 64 3 Neck Circumference: 37 4 Shoulder Width: 44 5 Chest Circumference: 94 6 Waist Circumference: 74 7 Hip Circumference: 88 8 Back Length: 67 9 Sleeve Length: 77 10 Upper Arm Circumference: 29 11 Elbow Circumference: 25 12 Forearm Circumference: 27 13 Wrist Circumference: 16.5 14 Inseam: 72 15 Below Knee Circumference: 33 16 Calf Circumference: 36 17 Ankle Circumference: 22 (Notes) 1.
