DESCRIPTION
Weighing in at just 10 ounces, the Lewis N. Clark umbrella is perfect for traveling and the everyday. Constructed of sturdy metal ribs and a 3-fold chrome-plated steel shaft, along with lightweight and flexible fiberglass tips, the rust- and corrosion-resistant frame offers protection against both rain and wind.

The water-resistant material as well as the ample 38in canopy ensure that you’ll stay as dry as possible whether you’re walking to your car or to the Eiffel Tower.

The accompanying mold-resistant sleeve effortlessly slips into totes, handbags, duffels, briefcases, and glove compartments, making it easily accessible no matter where you go. Additionally, the rubberized non-slip handle makes it easy to hold the umbrella against high winds.

With its automatic open/close button, you’ll have one hand free for holding your coffee, opening doors, pulling along your suitcase, or even talking on your phone. Additionally, the pressure required to open the canopy will ensure that it doesn’t accidentally open while it’s being jostled around in your purse or bag.
