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 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 prevent water intrusion and improve 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.
