The canopy of the umbrella opens and closes with a simple push of a button. When you need it, push it open, then press it again to fold the canopy and manually lock it back into place. ? LARGER SIZE Our umbrella has a huge canopy that can easily handle two people while folding down to a small size that can be easily stored in your backpack. Despite its huge size, it is also lightweight. ? FIBERGLASS RIBS The Travel Umbrella is supported with ten resin-reinforced fiber glass wings that bend slightly to resist high winds without turning inside out and protects you from the elements like no other umbrella. ? WATERPROOF MATERIAL The umbrella's canopy is created of quality high density waterproof pongee fabric, which successfully prevents rains from seeping down, regardless of how forceful and rough the weather is.
