The reason "you can carry it long even though it's a folding umbrella." A detailed explanation of the 2-way structure and two modes.

This 2-way design allows you to carry your folding umbrella at full length. In this article, we will focus on the rib structure used in the "2WAY HEATBLOCK Aluminum Silver" and explain its mechanism and usability in detail, with accompanying images.

1. [Short Mode] Compact form for storing in a bag

First, there's the "Short Mode" for storing it in your bag. This product uses a "two-stage folding, manual open (snap-button type)" structure, which was once standard.

While most modern folding umbrellas automatically fold into three sections when the shaft is retracted, this umbrella requires you to manually fold each rib one by one for storage.

  • Structural advantages: Compared to a three-stage type, it has one less joint in the ribs, which reduces the overlap of the fabric when folded, making it incredibly slim.

2. [Long Mode] For frequent use

The true essence of this product lies in its "Long Mode," where the main ribs are bundled without being folded. This is the most rational form for parasol users who repeatedly open and close their umbrellas to avoid the sun throughout the day.

  • Two name bands: This umbrella comes standard with "two straps," one for when it's short and one for when it's long. After retracting the shaft, simply secure it with the longer strap without folding the ribs, and it becomes like a long umbrella.

  • Convenience points: Since there's no need to fold the ribs every time, you can quickly prepare for the next sun exposure. Also, when used in the rain, there's no need to touch the wet fabric and get your hands wet while folding; you can simply bundle it up and store it, which is a significant advantage.

3. [Bag Usage] Dedicated storage bag with adjustable length for each mode

The included dedicated storage bag maximizes the convenience of "folding in two ways." This bag can be adjusted to the optimal length for each umbrella mode (short or long).

  • Two-stage adjustment with snap buttons: There's a snap button in the middle of the storage bag, allowing you to secure it at the optimal size for each mode.

    • In Long Mode: Unfasten the button to extend the bag. The full-length umbrella fits perfectly, making it suitable for hanging on a bag handle or carrying as is. In this state, there's no need to use disposable plastic umbrella bags found in stores.

    • In Short Mode: Fold the bag over and fasten the button to quickly transform it into a compact size. The excess bag won't get in the way when storing it in your bag.

Summary: A structure that sought the "optimal solution" for a parasol

"A folding umbrella that can be folded while remaining long." This 2-way design redefines the seemingly analog "snap-button type" structure to suit modern lifestyles.

Compared to a three-stage umbrella, the overall length when folded is inevitably a bit longer. However, this achieves an "overwhelmingly slim" profile, so it won't get in the way in your bag or hand.

  • Light and easy in long mode while traveling or out and about.

  • Slim in short mode when stored.

This structure, which allows you to switch between "forms" depending on the use, can be said to be a complete form for making daily travel smoother.
