Made with Sunny Energy® special material!

●The ingredients are special inorganic nanoparticles derived from natural minerals, and the effects are long-lasting.
●Demonstrated to raise temperature by up to +10 degrees in approximately 5 minutes.
The most notable feature of Sunny Energy is its reliable heat storage and heat retention function. Compared to general fiber materials, it has been proven to increase the surface temperature by up to 10°C or more, although there are differences depending on the fabric, such as woven or tricot.
Furthermore, even in the evening or on cloudy days when the light intensity is weaker, it efficiently absorbs small amounts of solar energy and demonstrates its functionality.In actual testing, when the temperature rise was confirmed after about 5 minutes of exposure, it was proven that it has a heat storage and heat retention function that is about 4°C higher than other heat storage materials.
●It dries twice as fast as regular polyester, so you can use it safely even on snowy mountains.
When ordinary polyester and SUNNY ENERGY were soaked in water and exposed to sunlight, the time it took for the moisture content to drop below 10% was compared. It was found that SUNNY ENERGY took 19 minutes to dry, compared to 32 minutes for polyester.
●UV protection - Stores heat and blocks UV rays, making it ideal for sun protection.
SUNNY ENERGY has heat storage and insulation properties, but also has excellent UV protection. It effectively blocks UV rays that shine down on people regardless of the season, and wearing it can also be expected to prevent sunburn.

This is sure to be an indispensable item for cold winters, snowy mountains, and outdoors.
