Breathability Increased by 400%! Mizuno's Functional Underwear "KARUAIR" is Smooth, Light, & Cool

In order to survive the extreme heat, functional wear with quick sweat absorption and drying is indispensable. However, even these functional wears tend to feel sticky after a large amount of sweat has dried. The quest for sweat-absorbing, quick-drying, and cool wear that maintains a smooth and comfortable feel continues this year as I buy and test new products from sports and outdoor shops.
 
I bought the newly released "KARUAIR" from Mizuno for the 2024 spring/summer collection and wore it under a three-quarter sleeve shirt as underwear. I was amazed at how much cooler it felt compared to just wearing the shirt alone, and there was no stickiness even after the sweat dried. Most importantly, it was light and didn't feel bulky despite layering. Intrigued, I visited Mizuno Corporation and talked to Masanori Inoguchi from the Global Apparel Product Division, Global Planning & Design Office, about "KARUAIR."
