4. Hard mesh for breathability and stain resistance
The vest is essential to work on scorching hot days, but it is difficult to wash every day. With hard mesh material instead of cloth, our vest delivers a solution to the problem, providing not only breathability and but also stain resistance for less washing.

Water + Multiple additives + Water absorptive polymer
→ Superior in stability of optimum temperature for human and of long cooling time.

Common ice pack:
Water + Water absorptive polymer
→ Cold retention effect the same as water or ice
