Japan's summers have reached a level that threatens life itself, making traditional methods like hydration and standard 'contact-cooling' innerwear insufficient. Most previous countermeasures were merely reactive treatments after the body had already overheated.
## Why Conventional Cooling Innerwear Fails
'Contact cooling' only addresses heat transfer at the moment of contact with the fabric. Near-infrared rays, which make up about 50% of sunlight, penetrate typical innerwear and heat the core of the body directly. This is the primary reason the inside of clothing turns into a sauna-like environment.
## The Scientific Thermal Shielding Mechanism of 'CORE SHIELD®'
Developed by PNX, 'CORE SHIELD®' incorporates 'CWO®', a special ceramic nanoparticle developed by Sumitomo Metal Mining, into its fibers. CWO® is an ultra-high-performance thermal shielding material used in aircraft and advanced building windows. Through this technology, the product has successfully suppressed temperature rises inside clothing by up to 2°C, even under direct sunlight.
FAQ
What makes CORE SHIELD® different from traditional cooling innerwear?
Unlike traditional cooling innerwear, CORE SHIELD® has the function of physically blocking near-infrared rays (heat rays), which are a cause of heatstroke.
What special material is used in CORE SHIELD®?
CORE SHIELD® uses a special ceramic microparticle called 'CWO®' developed by Sumitomo Metal Mining Co., Ltd.
Where is the CWO® material used?
CWO® is used in places where extremely high heat-shielding performance is required, such as aircraft, luxury cars, and windows of cutting-edge high-rise buildings.
What effects can be expected from wearing this innerwear?
Even under direct sunlight, it can suppress the temperature rise inside the clothing by up to 2°C, preventing the body's core from warming up and reducing the risk of heatstroke.
Why can't traditional cooling innerwear prevent heatstroke?
Traditional cooling innerwear only relies on heat transfer at the skin surface and allows near-infrared rays in sunlight to pass through, warming the deeper layers of the skin, which does not fundamentally solve the problem.
