Prolonged sun exposure is not good for your skin. Made of UV-proof polyester, this parasol safeguards your skin health by blocking most of the UV light. This umbrella is much more stable thanks to its single wind vent that allows wind and air to vent through the canopy. And the heat and hot air accumulated under the canopy can escape through the vent as the cooler air comes in, so that you feel much more comfortable. This product ships in approximately 1 days
