SUNAYAMA Corporation (Head Office: Katsushika-ku, Tokyo; Representative Director and President: Naoki Sunayama), which bases its development on coldness, posture, and good sleep, is expanding its sustained cooling item, the "Xylimint Series."
Amidst the Japan Meteorological Agency's prediction of a nationwide trend towards high temperatures in the summer of 2026, the series is attracting attention.
While general "contact cooling" materials are characterized by "coldness the moment they are touched," "Xylimint" features a "sustained cooling" specification that maintains coolness in reaction to sweat.
With mint and xylitol processing, it is designed to feel cooler the more you sweat, responding to needs for extreme heat countermeasures during commuting, outdoor travel, walking, sports spectating, and more.
◆ Focused on the problem of "cooling items are only cold at first"
In recent years, while "contact cooling" items have become a summer staple, voices have been increasing saying:
"It's only cold at first"
"The coolness disappears as you wear it"
"I'm not satisfied with UV and extreme heat countermeasures"
Therefore, we focused on the "persistence of coolness."
◆ Lasting cool sensation
The "Xylimint Series" is a series aimed at sustained cooling, with xylitol that reacts to sweat and mint that causes a sensation of coldness processed into the fabric.
◆ Responding to "stress from outdoor activities" in extreme heat
Due to the recent rise in extreme heat, "outdoor activities" themselves have become a major stress not only indoors but also outdoors.
Especially in summer, activities like:
Walking to the station
Cycling to work or school
Pick-ups and drop-offs
Outdoor events
Sports spectating
Sports
Gardening and farm work
—being exposed to strong sunlight and sweat has become a daily occurrence.
Also, in recent years, UV protection is attracting attention not only for "beauty purposes" but also as a countermeasure against fatigue as well as heat.
It is suggested that protecting the skin from UV rays can lead to a reduction in fatigue during and after exercise.
◆ Product Information
Block UV rays and heat for areas of concern.
We offer 6 types of items.
Longer length for thorough coverage, even the back of the hands, which are prone to forgetting sunscreen, are thoroughly covered.

The palms are open, making it easy to operate a wristwatch, and useful when sweat stains or chafing are a concern.
