A reenforcing annular ring is provided along the outer edge of the inside of the canopy of an umbrella. The reenforcing ring is made of a flexible, cloth-like material with its outer portion fastened to the panels of the canopy. The inner portion of the reenforcing ring is fastened to a ring of strong flexible rope that secures the reenforcing ring and the panels of the canopy against outward flexing in a high wind.
