This is the TECH FLEX JERSEY VEST from the 25ss collection. I purchased it from the official website and have only worn it about four times, including trying it on. While it's in near-new condition, it's been over six months since I bought it, so there might be slight signs of wear or deterioration. Please refrain from purchasing if you are overly sensitive to these details, and please consider that it is a used item! I am also listing it on other sites, and I will remove the listing if it is purchased there. Please ask any questions in the comments! The following is a quote from the official site: This is a simple stand-collar zip vest made with super-stretch material. It has a relaxed silhouette, but it's a cut vest that can be layered. It will be useful in various situations. It's the perfect piece for after fishing. It stretches 360° in all directions, and the super-stretch twill material pursues ease of movement and comfort. It is a material that combines a soft texture and quick-drying properties.
