Also available at OSHMAN'S, The RLM RUBBER semi-dry full suit. ttps://www.threeocean.info/ ttp://www.alpha-surf.jp/news/22685.html ttps://www.oshmans.co.jp/wetsuit_selection2018fw/therlmrubber It's 3mm, but since it's a semi-dry suit, it's not suitable for the dead of winter. However, it can be comfortably worn in early winter in the Kanto region or around March. I wore it comfortably on December 10th in Shonan around 6:00 AM (5℃ to 10℃). While 5mm semi-dry suits are certainly warm, they inevitably restrict movement. On the other hand, a 3mm jersey full suit is easy to move in, but it doesn't provide enough warmth for surfing... A 3mm semi-dry suit combines the strengths of both, and it's perfectly fine even in the current water temperature, unless it's extremely cold (of course, it depends on the region...). The fabric is still plenty soft, and I am particularly confident in the softness and heat retention of the skin material used (it's costly). I don't feel the need for repairs as far as I've worn it, but I did feel some water seeping in at the knees, though not the crotch. As shown in the image, the rubber on the flap has become unsightly due to ozone cracking, so I applied a generous amount of National Bond to both shoulders. I just applied it haphazardly, so it doesn't look great, but as you can see in the image of the inside, there are no holes, and it can be used normally. If you're worried, you can wear an inner neck, which is also sold online, beforehand for peace of mind (I didn't buy one because I didn't need it). It was custom-made to fit 168cm/62Kg. As a guide, it should fit someone around 170cm, 60-65Kg (M-ML size) (although it depends on body type). • The suitability of a wetsuit depends on your body shape. We naturally cannot accept returns due to "it was bigger (smaller) than I thought." Some people leave negative reviews out of spite, but we will report such malicious behavior to Mercari.
