The wind umbrella features an innovative one-button opening and auto-closing design. At 11.5 in length when closed, our lightweight black umbrella (15.63 oz) fits in your backpack, briefcase or to carry everything with ease. Keep it in your car for sudden storms and keep it handy for long walks in the rain.Wind resistant, double ventilation, 9-rod awning: cover yourself in the rain with our small, wind-defying, double-ventilated 9-rod umbrella. Unlike similar umbrellas with 6 or 8 rods, our 9 fiberglass rods remain stable in strong wind gusts, and the double-ventilated Teflon-coated awning allows wind to pass through while providing superior moisture protection.
