UNIQLO has launched their 2014 Fall Winter HEATTECH lineup for men, women and kids. Among the range of enhancements for the extensive collection of 253 items, is an increase in the number of garments featuring HEATTECH Extra Warm, a technology that offers around 50% greater warmth than regular HEATTECH. 

'The popular UNIQLO mainstay HEATECH, provides improved comfort and functionality this season'

UNIQLO’S HEATTECH Extra Warm line debuted in 2013 following customer feedback asking for the benefits of HEATTECH that will work in the coldest weather.

HEATTECH Extra Warm offers adjusted knit and thicker fabric for a napped finish that creates a layer of air against the skin to provide around 50% greater warmth than the regular HEATTECH products. Also in response to customer feedback, they added a turtle neck, V-neck and tights for men as well as leggings for women as part of the Extra Warm range of items. 

UNIQLO enhanced HEATTECH’s comfort by lengthening the stitch loops of the fabric for greater structural elasticity – it now stretches by up to 25% in any direction.

This reduces resistance when putting on and removing which improves comfort. At the same time, the new micro-rayon fabric for men's and women's lines results in an even smoother texture. From 2013, UNIQLO has blended Camellia oil, which is used in cosmetics and other products, into HEATTECH as a moisturiser. 

This year, they have incorporated 30% more Camellia oil for an even softer feel to fight dry skin through the Winter. Finally, they have continued with HEATTECH sweaters featuring carbon woven into the fabric which absorbs sunlight and converts it into thermal energy.

For 2014, they've also extended the men's and women's line including new long boxer shorts for men.  

The calculation for greater warmth in the HEATTECH Extra Warm line is based on the clo value, which measures the thermal resistance of a garment. The tests conducted by UNIQLO based on the ISO 9920 standard showed that HEATTECH Extra Warm is 40% warmer than HEATTECH innerwear for men and 60% for women.
