According to the Japan Meteorological Agency's warm weather forecast released in February this year, a heat wave is expected to arrive again this year... When you have to go out, even in extreme heat, you want to stay as cool and comfortable as possible. In extreme heat, it is important not only the temperature but also measures against ultraviolet rays. In fact, exposure to ultraviolet rays not only damages the skin but also causes fatigue. For this reason, many people use parasols to avoid exposure to ultraviolet rays as much as possible. However, depending on the design and color of the parasol, it absorbs the sun's rays, and the inside of the umbrella heats up and becomes very hot. It would be nice to have an umbrella that can block ultraviolet rays and stay cool. This time, I would like to recommend "GeeBrella-Fan" to everyone. GeeBrella-Fan is a "rain and shine umbrella with a built-in fan". When you open the umbrella, there is a small fan built into the center! Even on a very hot day, such as a summer day, if you run the fan, you can lower the perceived temperature, so you can spend a very comfortable time!
