Adult MLB Caps

They're the three main New Era fits:

• 59FIFTY: the fitted, structured cap with a flat visor, sold in exact hat sizes. The Authentic Collection 59FIFTY is the same cap MLB players wear on the field.

• 39THIRTY: a stretch-fit cap with a curved visor, sized S/M, M/L or L/XL.

• 9FORTY: an adjustable cap with a strap or snap closure, so one size fits most.

Wrap a soft measuring tape around your head, about 1 cm above your ears and across your forehead, and note the measurement. Then compare it with the brand's size chart: for example, a head of about 58 cm usually fits a 7 1/4 fitted cap. If you're between two sizes, go up a size. Not sure? Try a few fitted caps in store in Laval, Saint-Hubert or Ottawa.

A Low Profile 59FIFTY has a shallower crown than the standard 59FIFTY, so it sits closer to the head. It's a popular choice for people who find the regular authentic cap too tall. We carry Low Profile versions of team caps like the Toronto Blue Jays and New York Yankees.

Yes, they're our biggest selection. Choose from Blue Jays home, alternate and City Connect caps, plus classic Montreal Expos game caps from the 1969–91 and 1999–2004 eras. Complete your look with a Blue Jays jersey or tuque.

Cooperstown caps bring back historic team logos and colours, like the original 1977–88 Blue Jays logo. City Connect caps match MLB's alternate City Connect uniforms, designed to celebrate each team's city and culture. Both are popular with collectors and fans who want something different from the standard game cap.

Don't put your cap in the washing machine or dryer, which can warp the visor and crown. Spot clean with a damp cloth and mild soap, then let it air dry on a rounded surface. To keep the shape, store it on a shelf or hook rather than crushing it in a bag. Fans of '47 and New Era can find more styles from '47 and New Era.
