This is a semi-dry (5/3mm) wetsuit. The model is "ZIP FREE". It was custom-made in 2021 and used for four seasons until 2024. I am 171.5 cm tall, weigh 61 kg, have an 88 cm chest, and a 76 cm waist. The rubber on both chests is worn from paddling. The right side (facing) shows a bit of the lining. The left side hasn't reached the lining yet. On the inside of the right side, there's an iron-on patch to prevent tearing, so water doesn't get in much. The left side hasn't reached the lining, so it doesn't leak. There are patches on the inside of both armpits to prevent tearing. There are no other major tears, but there is some peeling at the seams of the rubber, which is expected with age, so I've repaired it in places with wetsuit glue. The back of the right knee has some fuzziness because I had a leash abrasion pad there, but there's almost no wear or tear. The chest zipper works smoothly without any problems. Elbow pads were added as an option to prevent tearing. The knees are made of tough jersey material. The lining uses a moisture-absorbing and heat-generating material for the base fabric, with lightweight, insulating hollow fibers softly knitted on the surface, and capsaicin processing to enhance heat retention. It's a brushed jersey called "STRONG DRY". I think it can still be used if you don't mind the appearance.
