What is the main feature of the 'MFU1S'?

Its '1-second storage' feature. When you close the umbrella, special internal panels work to automatically and neatly form the creases in about 1 second. No manual folding is needed.

What are its basic capabilities as a sun umbrella?

It offers 100% light blocking, a 100% UV cut rate (UPF50+), and protects your skin from strong ultraviolet rays. It also provides a cooling effect of up to -20°C, like being in the shade of a tree.

It's KONCIWA's original character. Attached to the umbrella's strap, it changes color from white to purple when it detects UV rays, visually alerting you to the strength of the sun.

MFU1S

KONCIWA (Headquarters: Bunkyo-ku, Tokyo), as an evolution of its highly acclaimed shape-memory folding umbrella series from 2025, will release its latest model, the "MFU1S," with further enhanced storage convenience, starting in 2026. ■ Development Background | Addressing the User's "Folding Stress" The 2025 model "MFU5S" gained the support of many customers for its innovative convenience of "folding in 5 seconds." For the 2026 model "MFU1S," we have further deepened that value and pursued a new experiential value: "neatly folded in 1 second." By creating a structure where the fabric naturally settles as the umbrella is closed, we have elevated the everyday action itself into something smarter. This model embodies an "artisan's dedication to improvement" that goes beyond mere performance enhancement to beautify even the user's gestures. ■ Key Features of the "MFU1S" 1. 【Innovation】 "1-Second Storage" Completed the Moment It's Closed Special PET panels built inside work in conjunction with the opening and closing of the umbrella, guiding the fabric to its ideal creases. Zero Effort: There is absolutely no need to smooth out the folds by hand. Lasting Beauty: The panels maintain the shape stably, preserving comfortable storage for a long period.

2. 【Top Class】 100% Complete Light Blocking × -20°C Heat Reduction Employs a 4-layer high-performance coated fabric that achieves both high-level light blocking and heat reduction.

Heat Reduction Performance: Demonstrates a maximum of -20°C heat reduction effect under direct sunlight, providing a coolness like being in the shade of a tree.

UV Protection: UPF50+, 100% UV cut rate. Firmly protects the skin from intense ultraviolet rays.

3. 【Practicality】 Highest Grade 5 Water Repellency & Safety Design All-Weather Ready: Achieved the highest Grade 5 in water repellency tests. It instantly repels raindrops, making it active all year round for both sun and rain.

Anti-Rebound: In addition to one-touch automatic opening and closing, it features a safety design that prevents the shaft from suddenly springing back during retraction.

4. 【Unique Charm】 "Kon-chan" Visualizes UV Rays Features KONCIWA's original character, "Kon-chan." When it detects ultraviolet rays, its color changes from "white to purple," a specification that combines functionality and playfulness by allowing you to visually confirm invisible UV rays.

5. 【Excellent Portability】 Multi-functional Pouch for Greater Freedom The included storage pouch has been improved with a thorough pursuit of ease of use down to the details. With Handle: Can be carried smartly on its own. Equipped with a Hook (clasp): Can be attached to the outside of a bag, reducing stress from wetness.
