Major League Baseball directs 100% of its royalties from on-field 9/11 Remembrance caps to MLB Charities, a 501(c)(3) nonprofit. MLB Charities will then donate those funds to the National September 11 Memorial & Museum and 9/11 Day. The San Francisco Giants wore this special 9/11 Memorial 59FIFTY fitted hat during their game on Sept. 11, 2021, in commemoration of the events that took place that day in 2001. This fitted hat features a memorial ribbon patch on the side of the hat. With the fitted design, you can find the perfect fit for your size.
