No one's a bigger New York Mets fan than you and that'll be clear when you rock this special 2024-Armed Forces Day On-Field 59Fifty Fitted Hat from New Era. Major League Baseball directs 100% of its royalties from on-field Armed Forces Weekend socks and caps to Mlb Charities, a 501 c 3 nonprofit. Mlb Charities will then donate those funds to several organizations that support active service members, veterans and families in the areas of inclusivity and essential resources.
