Choosing to Carry Ice: Direct Cooling Device 'Hyōnō' Launches!

Summer heat silently accumulates in the body.

A few minutes walking to the station, a brief moment waiting at a traffic light—the inescapable heat gradually raises your body temperature. This experience is all too familiar for many.

At such moments, what people truly need isn't just a 'cool feeling,' but a tangible sensation of cold.

HAGOOGI Inc. introduces 'Hyōnō,' a portable direct cooling device born from the idea of 'carrying ice itself.'

Instead of cooling with air, it delivers actual coldness directly to the body.

Unlike conventional indirect cooling methods, 'Hyōnō' uses ice and water to directly cool the body, enabling rapid cooldown even when you're out and about.

It's more than just cooling—it's a proposal to carry with you the act of 'returning your body temperature to normal.'

Recently, the need to 'cool down instantly' during commutes, school trips, or outdoor activities has been growing. However, air-based cooling is highly affected by ambient temperature, and cooling accessories often provide only temporary relief.

HAGOOGI focused on a simple concept: 'carrying the cold source itself.'

'Hyōnō' is a portable cooling device that works simply by filling it with ice and water.

By placing it directly on high-blood-flow areas like the neck or wrists, it delivers the chill of ice directly to the body, supporting quick cooldown anytime, anywhere.
