Yes, the style of a jacket can affect how much warmth and insulation you’ll get in the jacket. Depending on where you’ll be when you are outdoors and how cold the weather gets, you’ll need to consider your style of jacket accordingly. If you plan on experiencing temperatures of 30 degrees Fahrenheit or less when outside, then you’ll want a midweight to heavyweight jacket style because they offer more warmth potential. However, if you plan on being outdoors when the weather is between 30 to 60 degrees Fahrenheit, then you can consider an ultralight jacket or a sweater to meet your needs. Knowing what the temperature is likely to be when you are active outdoors should help you dictate what you need.
