This product is equipped with functions to block ultraviolet rays, visible light, and near-infrared rays, supporting a comfortable wearing environment even in summer by suppressing the rise in internal clothing temperature.

**■ Development Background: Developed against the backdrop of increasing demand for functionality to work comfortably even in extreme heat**

In recent years, against the backdrop of rising summer temperatures and an increasing number of scorching hot days, interest in heat countermeasures and comfort has grown even in business settings. Especially during commuting, going out, and moving outdoors, there is a demand to mitigate the rise in internal clothing temperature due to sunlight and reduce discomfort caused by sweat.

Furthermore, for summer business wear, there is a growing need not only for comfort but also for practicality, such as ease of care to maintain a clean appearance and consideration for sheerness.

To meet these market needs, our company has adopted the heat-shielding functional material "Heat Guard" for a dress shirt that can be worn comfortably and with peace of mind daily, while reducing the effects of sunlight.

**■ Product Features: Equipped with various functions to make summer business scenes comfortable**

**1. Triple Function to Reduce UV, Visible Light, and Near-Infrared Rays** Achieves a triple function that reduces ultraviolet rays, visible light, and near-infrared rays by using full-dull fabric. In addition to UV rays, it reduces visible light, which causes sheerness, and near-infrared rays, which lead to a rise in internal clothing temperature, thereby mitigating the effects of sunlight. This specification is designed to create a comfortable wearing environment even during the hot season.

**2. Heat-shielding performance that suppresses the rise in internal clothing temperature** By reducing near-infrared rays, it suppresses the intrusion of heat from sunlight and alleviates the rise in internal clothing temperature. It supports a comfortable wearing experience in situations exposed to strong sunlight, such as commuting and going out.

**3. Easy care with shape-retaining (easy-iron) specifications** It has been treated with a shape-retaining finish that reduces wrinkles after washing, minimizing the effort of ironing. It is easy to handle in a busy daily life and offers practicality to maintain a clean wearing condition.

**4. Cool-touch function for the inner collar for a refreshingly comfortable neck** By using a cool-touch functional material for the inner collar, which often comes into contact with the skin, it provides a refreshing sensation when worn, reducing discomfort around the neck. This supports a comfortable wearing experience, especially during commuting and going out in sweaty seasons.

**5. Sense of security due to reduced sheerness** By blocking visible light, it reduces sheerness, which tends to be a concern in summer, allowing you to wear it with confidence. It supports a clean and appropriate appearance for business scenes.
