Our Values
We believe in doing the right thing, even when it’s hard. We show integrity and respect to our customers, team, and fellow American partners. We don’t promise, we prove.
100% Made in America
When we say 100%, we mean 100%. We source only the best materials from manufacturers across America—then it all gets sewn and assembled right here in Charleston, South Carolina.

With our Hand Over Our Heart
We craft premium American-made products with a deep respect for tradition. Don’t settle for flags produced outside our borders.

Great shirt and an even better design! Received lots of compliments
Fits well and looks nice
Wanted to love the t-shirt, but it was far too long and seemed very thin so I am actually returning it.
Just like Allegiance Flags, the two Tshirts I have from Allegiance Flag Supply are tough, hold their color and the fit is very natural. People see me wearing them and frequently comment how great they are. Keep it up! I love them! Coach Terry Hamlin
