Heattech is a brand of high-tech thermal clothing developed by the Japanese fashion brand Uniqlo. It is made of a unique blend of polyester, rayon, and acrylic fibers that work together to keep the wearer warm and dry in cold weather while also being relatively lightweight and breathable.
Heattech was first introduced by Uniqlo in 2003, in response to customer demand for warm yet affordable winter wear.
Since then, the brand has expanded to include a wide range of clothing items, from base layers to socks to outerwear.
Heattech is now sold globally, both through Uniqlo's brick-and-mortar stores and online.
In recent years, the brand has also added environmentally-friendly materials to some of its products, such as recycled polyester.

Heattech technology is a blend of fibers (polyester, rayon, and acrylic) that work together to retain body heat and wick away moisture, keeping the wearer warm and dry in cold weather.
Some Heattech products, such as those made with recycled polyester, are more environmentally friendly than others. However, the brand as a whole is not marketed as being particularly eco-friendly.
While Heattech products are designed to keep the wearer warm in cold weather, they can also be worn as base layers in other seasons, such as spring or fall.
Heattech products may shrink slightly in the wash, but the brand recommends following the care instructions on the product tag to minimize shrinkage.
Heattech products are available in a range of sizes, from XS to XXL, for both men and women.
