The world needed a better solution to the cold and UNIQLO decided to find it by challenging common sense. After years of working with world-class textile manufacturer Toray and creating over ten thousand samples, we came up with a totally new material to combat the cold.
This solution came in the form of a cutting-edge fabric which takes body heat and stores it within air pockets deep within the fibres to keep the wearer warm. This is HEATTECH.
The connotation with 'thermal wear' has always been thickness. But UNIQLO turned this on its head and asked the question: Why not make it as thin as possible? This formed the basis of HEATTECH. With garments as thin as 0.55mm, you can keep the warmth closer than ever.
THE PERFECT FIT
HEATTECH is made from a unique fabric which features amazing density. HEATTECH stretches to fit your body like a second skin, enabling you to keep the warmth closer to you than ever. The thinness and stretch of HEATTECH makes it one of the easiest and most unobtrusive forms of innerwear you will ever own. Providing a perfect base layer to any outfit, keeping you warm without compromise to your style.
HEATTECH EXTRA WARM features greater heat-retention properties than regular HEATTECH, and as a result is up to 1.5 times warmer. HEATTECH EXTRA WARM is made from a special fabric that features a unique knit construction and a napped inner surface for protection from the cold, making it an ideal choice for Winter sports or rugged outdoor activities, or just those who fancy that extra bit of warmth throughout the day.
