This is a 5mm dive jacket that I only used for one season. It's incredibly warm and excellent, but... I've gotten too big (muscle, probably) and my arms don't fit anymore (lol). It's a size S, and the fit is just right for someone around 48kg and under 154cm. The condition is good, so I'm listing it hoping it will be used actively in the ocean by the next diver. 【Features】 ・5mm thickness for excellent warmth ・Size S (for petite individuals) ・Stylish slick suit design ・Arm zippers for easy on and off ・Used for only one season This is a sale item, and returns are not accepted, so please confirm before purchasing.
