High-quality local core brand from Ohara, Chiba Outer-Boso: Sabare Wetsuits neck-entry semi-dry suit. Used for three seasons, from mid-December to March, only once a week for 3 hours per session during the dead of winter. Originally a shortboarder, I used it for SUP until recently, so there is no wax residue or deterioration around the seat. However, paddling on the SUP caused abrasion on the shoulder and armpit area. Therefore, I initially ordered that part with rubber skin, and replaced it with the same rubber skin in the second year. After the third season, it was worn out again. This neck-entry type combines both mobility and heat retention, but considering the deterioration of the stretching and shrinking due to aging, I replaced the shoulder joint area with jersey material after the season ended. I haven't used it since then, so that part is brand new (see the image of the part where the color of the brushed lining is different when turned inside out). Also, because it's a neck-entry type, there is little water intrusion, and the rubber skin panels on the chest and back are 3mm (not cold, and if it were 5mm, changing would be super hard), and everything from the waist down is 5mm except for the sleeves (3mm). The size is ML base semi-order. I am 169cm tall and weigh 58kg. I have a slender build, broad shoulders, and a dropped stomach, so I can't gain weight. Considering the deterioration of the rubber skin's elasticity... I recommend it to people who are 168cm or shorter, with a chest size of 85cm or less, and a waist of 74cm or less. If you are larger than that, changing will be difficult because it is a neck-entry type, so please be careful when purchasing. Color: Black Type of wetsuit: Semi-dry
