A blazer is a type of jacket. The term blazer occasionally is synonymous with boating jacket and sports jacket, two different garments. A blazer resembles a suit coat cut more casually — sometimes with flap-less patch pockets and metal buttons. A blazer's cloth is usually durable (14oz.), because it is an outdoor sports jacket. Stylistically, blazers often are uniform garments, e.g. for airline, school, and yachting, and rowing clubs.
A blazer is generally distinguished from a sports jacket as a more formal garment and tailored from solid color fabrics. Blazers are often made with naval-style metal buttons, reflecting their historic boating club association, but this is not a defining feature.
