Overview

An 8 foot beach and patio umbrella with 10 fiberglass ribs, a vented canopy, push button tilt, and a foldable sand anchor, built for shade at the beach, pool, or on soft ground.

The air vent design is meant to let wind pass through the canopy instead of catching it broadside, which is the usual failure point on cheaper beach umbrellas. Shade comes from a UPF 50+ rated, silver-coated fabric that the seller states blocks about 98 percent of UV rays, and the two-way push button tilt lets you angle the canopy without repositioning the whole umbrella.

  • 8 ft canopy with 10 fiberglass ribs
  • Air vent design reduces wind inversion
  • UPF 50+ rated fabric with silver coating
  • Foldable sand anchor with carry bag

Who it's for

Beachgoers or poolside sunbathers who want a large, portable umbrella with its own sand anchor, rather than a fixed patio umbrella on a weighted base.

Strengths and trade-offs

Drawn from this product's published specifications.

What stands out
  • Air vent design cuts wind catch and canopy inversion
  • Flexible fiberglass ribs resist breaking
  • Push button tilt angles shade without moving the umbrella
  • Foldable sand anchor packs into the carry bag
What to check first
  • Relies on sand anchor rather than a weighted base
  • No owner reviews yet to confirm wind performance

Performance notes

Ten fiberglass ribs are meant to flex under gusts rather than snap the way rigid steel ribs can, while the vented canopy panel lets air escape instead of ballooning the whole umbrella upward. The push button tilt mechanism moves the canopy through two directions so you can chase shade through the day, and the sand anchor folds flat into the included carrying bag for transport.

Frequently asked

Questions about the Ammsun umbrellas

Common buyer questions answered straight from the product spec data - no fluff, no "it depends".

Does the AMMSUN umbrella come with a base?

It includes a foldable sand anchor rather than a weighted stand, so it is built primarily for sand or soft ground.

How much UV protection does the fabric offer?

The seller states UPF 50+ protection with a silver coating that blocks about 98 percent of UV rays.

Can the shade angle be adjusted without moving the umbrella?

Yes, it uses a push button, two way tilt mechanism to angle the canopy while the umbrella stays in place.
