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 underarm 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 brushed materials, excelling in quick-drying, mobility, heat retention, and cost performance. For enhanced comfort during surfing, our semi-dry suits come standard with an inner neck, which prevents water entry and improves heat retention compared to traditional designs. We are committed to producing a product that satisfies our customers by paying close attention to every detail. #surfing #wetsuit #semidrysuit #fullsuit #longjohn #backzip #nonzip #chestzip #longchestzip #airflameboost Measurement Details: 1 Height 2 Weight 3 Neck Circumference 4 Shoulder Width 5 Upper Chest Circumference 6 Waist Circumference 7 Hip Circumference 8 Back Length 9 Sleeve Length (from center back of neck) 10 Bicep Circumference 11 Elbow Circumference 12 Forearm Circumference (below elbow) 13 Wrist Circumference 14 Inseam 15 Below Knee Circumference 16 Calf Circumference 17 Ankle Circumference (Important Notes) 1.
