A wide size product that increases the chest area by 2 and the waist by 3.5 sizes while keeping the length the same. This product demonstrates its best qualities when faced with the cold of changing weathers or when going downhill and receiving the brunt of the wind from upfront. It is pocketable and can be stored compactly, making it a convenient, portable item. While it fits closely to your body, the stretch material ensures easy movements and reduces fluttering caused by the wind. The back is made of mesh with excellent breathability. It has also been treated to be water repellent, making it resilient against light rain.
