It’s an origami umbrella!
Yes, you read that correctly. It’s an umbrella that is designed without a structural under-skeleton. Instead, the Sa umbrella uses a dual-canopy structure that utilizes planar tension to move free of the skeleton.
The canopies expand and contract in unison allowing the umbrella to open and close. Opening and closing is simple with a mechanism that rotates at the bottom of the handle.
