UNIQLO today announces that it will debut HEATTECH Ultra Warm innerwear at stores in Japan and at the uniqlo.com online store on December 19. UNIQLO developed this pinnacle of its HEATTECH line for people who live in frigid locations or who need to spend long times working outdoors in sub-zero temperatures.

The new line represents a major advance in the cold weather performance of HEATTECH, which has been pivotal to the LifeWear clothing range to deliver outstanding everyday comfort.

HEATTECH Ultra Warm is around 1.5 times warmer than HEATTECH Extra Warm and about 2.25 times warmer than regular HEATTECH. HEATTECH employs a special thread structure to trap warm air and increase heat retention as more air is stored. The enhanced performance of ULTRA WARM stems from a special knit design that differs from those of its previous HEATTECH counterparts. This design thickens the fabric and lengthens the fibers of the brushed lining.

Air pockets between the fibers create a large air layer within the fabric, whose raised fibers offer instant warmth as soon as you put the garment on. It is also comfortable when on the move even in the coldest climates, stretching and absorbing moisture. The fabric is soft and gentle on the skin to optimize comfort.

Notes:
1. The calculation compares UNIQLO offerings and is based on the clo value, which measures the thermal resistance of a garment. We calculated that HEATTECH Ultra Warm is 40% warmer than HEATTECH Extra Warm for Men's and 60% for Women's. Testing was based on the ASTM D 1518-85.
2. The calculation compares UNIQLO offerings and is based on the clo value, which measures the thermal resistance of a garment. We calculated that HEATTECH Ultra Warm is 125% warmer than HEATTECH innerwear for Men's and 125% for Women's. Testing was based on the ASTM D 1518-85.
