A deeper dome for more coverage.
The Prostorm’s deep 46” arc-diameter is less flat and offers more dome-depth than most other umbrellas. While an umbrella’s straight diameter measures the distance under the canopy, the arc-diameter will denote the depth of the umbrella’s dome. In general, a deeper dome will give you more coverage and more wind resistance than a flatter one.
