An A-frame hat is a distinctive style of baseball cap known for its elevated peak and sharply triangular silhouette. Its front crown panels are seamlessly integrated into one piece, creating a high-profile, pinched appearance that sets it apart. These hats usually feature a snapback closure for adjustable fit, but they also come in Fitted and Stretch Fit variations. Among these, the New Era 9Fifty Snapback is the most popular choice, renowned for its iconic design and versatile fit.
