This is a domestically produced full-suit 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. The jersey is a super-stretch jersey (relaxation jersey) developed jointly with a renowned Japanese textile company, offering excellent texture and elasticity. The combination of DT sponge and relaxation jersey creates the ultimate material. (Notes) The stretch long zipper is very delicate. When putting on or taking off the suit, please open and close it gently, ensuring that the slider does not get caught in the material, to avoid putting stress on the zipper. We are committed to producing this suit with attention to every detail to ensure customer satisfaction. #surfing #wetsuit #semidrysuit #fullsuit #longjohn #backzip #nonzip #chestzip #longchestzip #airflameboost L size details 1 Height 176 2 Weight 67 3 Neck circumference 37 4 Shoulder width 45 5 Chest circumference 98 6 Waist circumference 78 7 Hip circumference 92 8 Back length 68 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 Knee circumference 33 16 Calf circumference 36 17 Ankle circumference 22 (Notes) 1 Please note that we cannot accept cancellations, returns, or exchanges due to customer convenience. 2 Please ask any questions you may have before purchasing.
