Soft shell jackets can be good for winter, but their effectiveness will depend on the specific conditions you will be facing. Soft shell jackets are designed to provide protection from wind and light precipitation, while also allowing for breathability and ease of movement. This makes them a great choice for activities where you need to stay warm and dry, but also need to be able to move freely and stay comfortable.
In mild winter weather, a soft shell jacket may be all you need to stay warm and comfortable, especially if you are engaging in outdoor activities that generate heat and require a lot of movement, such as hiking, snowshoeing, or cross-country skiing. However, in more extreme winter conditions, a soft shell jacket may not provide enough insulation to keep you warm.
If you're planning to spend time outdoors in very cold temperatures or heavy precipitation, you may want to consider layering your soft shell jacket with other insulating layers, such as a fleece or a down jacket. You can also add a hard shell jacket over your soft shell layer to provide extra protection from wind and rain.
Ultimately, the effectiveness of a soft shell jacket in winter will depend on the specific conditions you will be facing, as well as your personal comfort preferences. When choosing a soft shell jacket for winter, look for one that is made from a thicker, more insulating material, and that has a water-resistant coating or treatment to help repel moisture.
