日焼け止めだけでは、太陽光対策は終わらない。

RECOGNIZED IN JAPAN

Spotlighted by Leading Japanese Media & Golf Press

Engineered in Japan and featured across major national newspapers and golf publications — CORE SHIELD® pioneers dual near-infrared and UV defense for extreme sun environments.

Desert fairways, outdoor sports, or layering under an Abaya or Kandura —
struggling with the UAE’s relentless sun and heat?Under the Emirates’ blazing skies, blocking UV rays alone isn’t enough to stop deep-penetrating solar heat from draining your energy.

Endless sweat and discomfort

That heavy, sweat-soaked shirt clinging to your skin… Sweaty hands slipping on the grip when it matters most… Feeling so uncomfortable you just want to go home early…

The toll on your body

Exhaustion hits the moment your round or work is over… The heat leaves you foggy, unable to focus or think clearly… Still tired after a full night of sleep, unable to do what you want the next day…

Worries about the heat

Outdoors with nowhere to escape, wondering “will I get through today okay?”… Every news report about dangerous heat makes you afraid to go outside… Worried that feeling unwell will make you miss work or important plans…

Beyond what sunscreen can reach

In fact,

“ Near-infrared rays ”

reach deep into your skin.

And they make up about 40% of sunlight.

What sunlight is made of: ultraviolet ~5%, visible light ~43%, near-infrared ~42%, other infrared ~11% What sunlight is made of: ultraviolet ~5%, visible light ~43%, near-infrared ~42%, other infrared ~11%
Beyond UV: Blocking the Heat You Feel

Near-infrared rays penetrate deeper into your skin than UV

  • Accounts for ~42% of solar energy—over 5x more than UV rays (~8%)
  • Passes through ordinary fabrics and turns into deep internal heat
  • Not blocked by standard sunscreen or conventional UV-cut innerwear

Less sweat after 18 holes.

The fabric is thicker than cooling shirts, so I was skeptical, but I clearly felt the difference on summer rounds. The burning feeling on the back of my neck eased, and I sweat noticeably less after 18 holes. I can't do without it now.

Like standing in the shade of a tree.

I could feel it keeping me cooler. Unlike cool-touch fabric, the coolness lasts. Especially when cycling and feeling the breeze, I actually feel cooler wearing it — just like stepping into the shade of a tree.

Better than I expected.

It kept the sun off and I stayed comfortable even under the blazing sun. I sweat more than most people, but it absorbed the sweat so it didn't run down. I also didn't get chilled by sweat when coming into an air-conditioned room. Better than I expected.

No more “piercing” sun.

Even with sunscreen, I was getting more sunspots every year. On my 20-minute bike commute, I no longer feel the sun piercing my arms and neck. I'm also happy that the high neck isn't uncomfortable.

Cool the moment I put it on — even in the summer fields.

I thought long sleeves for farm work were something you just had to put up with in the heat. This feels cool the moment I put it on, and even in the fields in midsummer I feel less worn out. Four stars only because I'd love a beige color option too.

“Wearable shade” for someone who dislikes air conditioning.

My son and his wife gave it to me after hearing that older people notice heat less easily. I don't like air conditioning, so it's like wearing shade. It's light and dries quickly after washing, so with two I can wear one every day. I see it as a tool for staying active for years to come.

Japan is known around the world for its uncompromising standards of quality and attention to detail. CORE SHIELD® carries that tradition into every piece we make.

Every step happens in Japan. The functional material uses special ceramic microparticles derived from rare metals. The fabric is produced in Japan, and each garment is sewn and packed by skilled craftspeople in Yanagawa, Fukuoka.

Our craftspeople use high-performance sewing machines also used for swimwear, creating a comfortable fit and seams that hold up wash after wash. Already worn by golfers, outdoor workers and daily walkers across Japan, and featured in Japanese newspapers including the Nishinippon Shimbun and Mainichi Shimbun — now available outside Japan.
