I bought a fancy Japanese umbrella by Mont Bell.
Fabric? Polkatex! I love the name — it brings a smile to my face. However, it might not communicate “strong waterproof fabric” in America like it might in Japan.
Sadly, when the user opens the umbrella, each strut has to be snapped into place — a small hassle. But it’s comforting to know that the waterproofing will last a long time!
