A slightly larger L size than the conventional Pentagon appears.
The diameter when opened is 7 cm larger.
Achieves the lightness of 79g even if the size increases.
In addition, the durability which can endure wind speed 15m / s, strong water repellant effect does not change either.
With the goal of developing an umbrella of 80 grams or less, we have reviewed the parts used from scratch.
The umbrella fabric is woven with 15 deniers, the same thickness as the yarn used for stocking, and the umbrella bone is made lightweight by combining it with a light and durable frame of carbon fiber and aluminum.
We applied the parachute cloth manufacturing method to the umbrella fabric, and woven it with 15 denier of the same thickness as the yarn used for stocking.
Umbrella bone is not made of conventional steel or glass fiber material, but has been changed to a combination of light and strong carbon fiber and aluminum to reduce weight.
Not only the lightness is the same frame design as the Pentagon 79, and the durability is the same.
We conducted an experiment using a wind speed of 15 m / s, and we found that there was no damage.
The coating that maintains strong water repellency is "Easy-Dry". By modifying the water repellent into fine particles of nano class, the water repellent coating penetrates deep into the fiber and becomes difficult to peel off.
