2.2X warmer and thicker than regular Heattech, HEATTECH ULTRA WARM is our warmest Heattech, which makes it best for intense cold.

UNIQLO’s Ultra Warm Heattech is even warmer than the Extra Warn variety - 2.2x warmer in fact. Designed for intensely cold weather, our selection of tops and bottoms are built to tackle harsh climates so it’s perfect for snow days, après ski holidays and all-round falling temperatures. Stock up on the variety of colours so you’ll always have some to hand.
