1mm thick inner made of a highly insulating brushed material made from hollow fibers. When worn under a 3mm jersey, it becomes an item equivalent to a 4/3mm thermal wetsuit. Recommended heights are as follows: XS 151-161cm S 155-165cm M 163-173cm L 172-182cm XL 177-187cm For surfers who want to enjoy the good waves of winter!! If you purchase with other items, all items from the second one will be discounted by 100 yen, so if you request a combined purchase, I will adjust the price♪ 3 items together >> 200 yen off the total 10 items together >> 900 yen off the total, etc. I am selling at a low price, so further discounts are often difficult, but I will offer further discounts if you pick up in Ikebukuro, Tokyo, Nishi-Funabashi or Makuhari in Chiba, or Kujukuri, or if you purchase multiple items or combine with other products, so please comment before purchasing. Discounts are also available for combined purchases with the following colleagues' and shop accounts. https://jp.mercari.com/user/profile/881481801 https://jp.mercari.com/user/profile/664097035 https://mercari-shops.com/shops/DjT4hJTNKm5Se6nFVAqkyc Please be sure to read the profile before purchasing♪ I am selling a lot of surfing goods!
