Semper Fidelis. 250 years. The Marine 250th Anniversary Baby Onesie is the perfect patriotic gift for the Marine Corps family welcoming a new baby into a household of service, sacrifice, and the Semper Fidelis commitment that has defined the United States Marine Corps for two and a half centuries. Whether you are a Marine family celebrating the 250th anniversary of the Corps with a new little one, shopping for the Marine veteran in your life who has a new baby in the family, or simply someone who believes that the Marine Corps legacy deserves to be honored from the very beginning, this military baby onesie is made for the newest member of the Marine family.
Available in multiple baby sizes. Please refer to the size chart before ordering and allow up to 1 inch variance due to the handmade production process. For a relaxed fit with room to grow, consider sizing up one size.
This baby onesie carries the Marine Corps 250th anniversary legacy in a design that honors the Semper Fidelis commitment and the 250 years of service with the patriotic pride they deserve. The USMC anniversary graphic is printed with bold, high-resolution digital ink that stays sharp and vibrant wash after wash. The airlume combed ringspun cotton is softer and stronger than standard cotton, making it ideal for the baby who is being raised in a Marine Corps family.
