Can two people fit comfortably under the umbrella?

I am 5’4” and 157lbs and two of me would fit comfortably under it. I will share that while I still think this is the best umbrella I have ever owned, pushing the top part back down requires two hands for me. The button collapses it nicely but still have to push it down to store. This is not a issue for me just wanted to share that.

What is the size of the umbrella's canopy?

Our canopy has a 40" diameter, which is significantly larger than most travel umbrellas while still being conveniently compact when in a closed position. When designing our umbrella, we noticed that most travel umbrellas could not comfortably fit two people underneath, so we have sought to offer the perfect balance between rain coverage and compactness.

How does it fair in strong winds?

We have thoroughly tested our umbrella in varying degrees of windy weather from mild gusts to extremely windy conditions. It has always held up very well. PLEASE NOTE: In extremely windy weather it is possible that the umbrella can be blown inside out, but we have designed it to quickly pop back into place without incurring any damage to the umbrella itself. If you are in extremely windy conditions then wearing a raincoat may be the best way to stay dry since the rain will be on a strong horizontal angle. Safe travels!

Not windproof! Wind resistant at best. Lasted about 30 seconds at the Cliffs of Moher in Ireland. Flipped inside out and collapsed with springs, wires, and strings going everywhere. Returned them for a refund.
