Team monograms first appeared in 1894 when the Boston Baseball Club (the Boston Braves) - now the Atlanta Braves - became the first team to wear letterforms when they added a monogram-style device to their caps, followed by three more teams in the next season. In the late 1880s, a pillbox version of the cap becomes popular through the early 1900s before fading from use five teams revived the form in 1976 in celebration of the US Bicentennial. The merino cap topped with a star-like pattern was made by the New York sporting goods company Peck & Snyder. In 1860, the Brooklyn Excelsiors wore the ancestor of the modern rounded-top baseball cap, which featured a long peak and a button on top, and by 1900, the "Brooklyn style" cap became popular.

History Harry Wright wearing a baseball cap, circa 1863. Since the 1980s, varieties of the hat have become prevalent in the United States and many other nations, both for utilitarian (protecting the eyes from the sun) and fashion accessory purposes. The baseball hat is a part of the traditional baseball uniform worn by players, with the brim pointing forward to shield the eyes from the sun. The hat may be "fitted" to the wearer's head or the back may have elastic, a plastic prong-in-a-hole (multiple holes with one prong that can be inserted), Velcro, a zipper, or a tri-glide slide so that it can be quickly adjusted to fit different wearers' heads.

The front of the hat typically displays a design or a logo (historically, usually only a sports team, namely a baseball team, or names of relevant companies, when used as a commercial marketing technique). A baseball cap is a type of soft hat with a rounded crown and a stiff bill projecting in front.
