The sailor jumper is a piece that carries through days and seasons without ever losing its appeal. This one preserves the authentic heritage of the Binic model, with its 1x1 rib knit, round neckline and straight cut, all crafted in our French workshops. Yet it holds a secret for the end of the day: once darkness falls, its stripes, after being exposed to natural or artificial light for nearly three hours, begin to glow for about one to two hours. It is part of the glow-in-the-dark collection, allowing you to match this piece with the Minquiers Sailor Striped Shirt, the Beanie, and even your dog's jumper.
