A sports jacket is often considered a versatile, must-have item of clothing in any wardrobe. However, you may be surprised to learn that there are many synonyms for this popular jacket style. For example, you might refer to it as a blazer, which typically features a solid color and is tailored for a more formal look. A sport coat, on the other hand, is similar to a blazer but may include patterns or textures and is often made of heavier fabrics suitable for outdoor activities. A suit jacket can be worn as a sports jacket, but should not be mistaken for one, as a suit jacket is typically part of a formal suit ensemble.
