This is a domestically produced semi-dry long chest suit, meticulously crafted with attention to detail in its lining, sewing, specifications, and overall finish. The sponge used is based on the highest grade DT sponge from National Rubber Co., Ltd., a leading domestic manufacturer whose sponges are also used by renowned overseas and domestic brands. The lining is the highest grade AF Boost lining from Tortoise Co., Ltd. For enhanced comfort during surfing, an inner neck is standard equipment on our semi-dry suits. (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 and that no strain is placed on the zipper. We are committed to producing our products with meticulous attention to detail to ensure customer satisfaction. #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 to wrist) 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 (Notes) 1.
