Concave Flag – Custom Feather Flag with Curved Bottom
Concave Flag: A Unique Twist on the Feather Flag
When it comes to outdoor advertising, few tools are as versatile and eye-catching as the feather flag. Among the many variations of this popular banner, the Concave Flag stands out with its distinctively curved bottom edge. Unlike standard shapes, the concave flag features an inward-arched bottom that forms a smooth, semi-circular contour—opposite to the convex flag, which arches outward.

What Is a Concave Flag?
A concave flag is a type of feather flag with a bottom edge that curves gently inward, resembling a half-circle cut from the base. This unique silhouette adds a soft, flowing aesthetic that enhances visual appeal and distinguishes your message from conventional signage.


Concave vs Convex: What's the Difference?
While both concave and convex flags belong to the feather flag family, their lower contours create completely opposite impressions. A convex flag features an outward curve—pushing the shape forward—whereas the concave flag subtly draws the viewer’s eye inward with its reverse arc. This subtle design difference can have a big impact on brand presentation and visual flow.

Perfect for All Types of Events and Promotions
Whether used outside storefronts, at trade shows, sporting events, or public festivals, concave flags offer strong visibility from a distance. The inward curve not only creates a refined shape but also helps the flag flutter more fluidly in the wind, catching attention while remaining legible.
