This is a unisex reversible jacket. It can be worn as both a boa fleece and a nylon shell. I purchased it at the Helly Hansen shop in Kamakura. I intended to wear it after purchasing it, so I removed the tags, but I have never worn it and have kept it in storage. It's a Helly Hansen reversible jacket. Regarding the size, it has a shoulder width similar to a men's M-L, but the body width is wide and the length is short. The chest and body width are not very different. It's a unisex jacket that allows you to enjoy both a nylon and a boa fleece jacket in one. I tried it on this season, but unfortunately, my muscles have become incredibly large, making the shoulders, arms, and latissimus dorsi area feel tight, so I'm reluctantly selling it. There are photos of the tags, so please check the official website for the size details. This is a reversible jacket that allows you to enjoy two different styles, using Fiberpile, which is considered the original fleece. Fiberpile is a signature material of HELLY HANSEN, created to protect fishermen working in extreme cold. It features a classic boa-like texture and excellent heat retention. It's an environmentally friendly material made from recycled yarn from plastic bottles, and the ends of the pile are cut to shorten the nap, giving it a light touch. The design is based on the Grizzly jacket (commonly known as "Bear Jacket") developed for cold protection in the 1930s, and is expressed with Fiberpile and vintage-style woven fabric. Side A, where the Fiberpile is visible, allows you to enjoy the boa fleece texture. Side B, where the windproof fabric is on the outside, allows the boa fleece to trap dead air, providing even more warmth. The woven fabric part is filled with padding to increase heat retention. The cuffs and hem are ribbed for airtightness.
