Regarding sweatshirts suitable for different weather conditions, you can find options that cater to specific needs. For warmer weather, look for lightweight sweatshirts made from breathable fabrics like cotton or French Terry. These will provide comfort without causing overheating. For colder weather, opt for heavier sweatshirts made from fleece or thicker materials to provide insulation and warmth. Some sweatshirts may also feature removable or adjustable layers to accommodate changing weather conditions.
