Product Description

*Helmet not included.
Coolness for harsh summer job sites.
So-Kai-kun II is a heatstroke prevention and cooling product for those who wear helmets while working on hot summer job sites. The special fiber material cuts 99.9% of UV rays, suppressing sunburn even on sunny days. Furthermore, the external insulation design effectively blocks heat from reaching the neck.

Long hours of work in the summer heat can be physically draining and lead to decreased concentration on safety. So-Kai-kun II cools the neck, making work on hot sites more comfortable and is an indispensable item for summer.
It is especially recommended for outdoor work under the blazing sun, construction sites, civil engineering sites, agricultural work, and factories without air conditioning.

It has been confirmed that 3 hours after wearing, while the area from the head to the shoulders exceeds 37°C without wearing it, wearing So-Kai-kun II not only suppresses the temperature of the cheeks and ears but also significantly reduces the temperature rise around the shoulders.
Cooling the neck cools the entire body.

Coolness lasts for a long time with just 2 minutes of preparation.
Simply soak in water for about 2 minutes.
It's very easy to use.
(1) Soak in water for about 2 minutes (polymer quickly absorbs water).
(2) Attach to the helmet with Velcro.
Preparation is complete. You can start working immediately, even after arriving at the site on a busy morning.

Why is it so cool with just water?
The secret lies in the principle of evaporative cooling, where water absorbs surrounding heat as it evaporates.
The water stored in the special polymer slowly evaporates due to the outside air and body heat. This efficiently absorbs and releases heat from the neck, providing a natural and comfortable coolness that lasts.

In addition, the polymer used in So-Kai-kun II has excellent water retention, keeping moisture for a long time.
Since evaporative cooling lasts for a long time with a single soaking, there is no need to re-soak frequently, and the cool feeling lasts longer.
