Ideal for autumn walks, the sleeveless sports jacket will delight women who want to be warm without sacrificing their look. Lightweight and practical, it is perfect for those who superimpose layers of clothing and do not want too much thickness under the arms. If the sleeveless jacket is more suitable for a hike than an outing on the slopes, it will also meet the needs of cycling enthusiasts, who will wear it over a t-shirt or a long sleeve jacket. The interest of the sleeveless jacket is to keep your muscles warm, but also to let your skin breathe by evacuating perspiration. This is why it is important to choose it in technical materials adapted to the practice of a sport.
