Why wear a jacket without sleeves? Because you have so much more freedom of movement, while your upper body is well protected from the wind and cold! Bodywarmers are often filled with down or plastic padding, the outside is made of a material such as parachute fabric. But there are also bodywarmers made entirely of fleece. You see them mostly in the mid-season, when it is often not really worth bundling up (yet). They come in handy for outdoor activities like cycling, walking, hiking, and even horse riding. But even if you just want to get some fresh air, a bodywarmer will do the job just fine.
