[Workman] - Is -10℃ for real? Checking the perceived temperature of the "Ice Shock Cool -10℃ Printed Short-Sleeve T-Shirt" during a morning run.

I continue to run for health management, but summer is too hot! So, I tried the Workman short-sleeve T-shirt that claims to have a cooling performance of -10℃. Does it really feel like around -10℃?

The functional shirts from Workman are equipped with evaporative cooling and contact cooling

The author has made morning running a daily routine. They step outside around 6 AM, hoping to run during the cooler hours. Even so, by the time they return home, they are so drenched in sweat that their T-shirt could be wrung out. Although they have been enduring it, many days have temperatures close to 30°C even in the early morning, which has been quite tough.

While looking for cooling wear at the nearby Workman, the “Ice Strike Cooling (R) -10℃ Printed Short Sleeve T-Shirt” with a -10℃ label caught their eye. As described, it boasts "shockingly cool performance," suggesting it has an unbelievable cooling capability.

Checking the official Workman website, it mentions that the evaporative cooling function is combined with contact cooling performance. When touched indoors, it feels refreshingly cool compared to other T-shirts. Thinking, "This might help with the heat during running!" they decided to get it.

Their usual running attire looks like this

First, they tried running in their regular running gear for 10 minutes. The current time is 6 AM. Even at this hour, the temperature is already over 26 degrees, and as soon as they start running, they begin to sweat.

Running wear is made from breathable materials, but it also feels like heat gets trapped. When I return home as usual, my top and bottom wear are drenched in sweat. It's understandable since it's a hot summer, but my running time and performance drop compared to cooler periods.

Check the performance of Workman's T-shirt

After taking a shower, I reset my sweat-soaked body in an air-conditioned room! Now, let's finally check the performance of Workman's “Ice Shock Cooling (R) -10℃ Printed Short-Sleeve T-shirt.” The outside temperature at this time is 27℃. The temperature has risen since I started running, and the sunlight has also become stronger.

Indeed, it feels like -10℃! I can totally agree with this.

From the moment I put on Workman's T-shirt, I felt the coolness! When I actually run, the areas touching my skin on my back and arms feel continuously cool. Moreover, it’s not just a typical cooling sensation; it feels like I have a chilled, wet towel against my skin.

I see… This really is understandable as a -10℃ cooling performance. This alone has made harsh summer running significantly easier. I feel like I might be able to run for 10, or rather 15 minutes longer than usual.

What surprised me even more was when the wind blew. I experienced a punchy coolness, like when cooling spray is applied over clothing! Air enters through small holes that can be seen visually, so the breathability is excellent. The fabric is smooth and doesn't cling to the skin even when sweating, which makes it easy to move my body, and I really like that.

I have worn and washed it over ten times, but the cool feeling remains unchanged. It also has UV cut functionality, which is a great point since I can wear it with confidence even on sunny days. Honestly, I never thought I could buy such a cool short-sleeved T-shirt for 580 yen. I primarily use it for running and walking my dog, but I also recommend it for outdoor scenes where you'll spend a long time, like camping or watching sports.
