It's not double vented!,
Verified Purchase(What's this?)
This review is from: Totes Signature SuperDome Auto Open/Close Umbrella
It's not double-vented. It's not even single-vented! It's a nice big black collapsible umbrella that feels reasonably solid, but there's nothing remotely like a vent anywhere on the thing, so it's a mystery to me why this product is described as "Vented canopy for superb wind resistance" and "The Double Vented Canopy provides venting to help secure the umbrella canopy in strong wind."
