International clothing retailer UNIQLO today announces the launch of the first Uniqlo U HEATTECH items. The new long-sleeved crewneck shirts for men and women combine sophisticated style with innovative functionality. The thin but warm HEATTECH thermowear made its debut in 2003 and has been a customer favorite for years. Uniqlo U HEATTECH is available in-store and online today, Monday November 2.

Uniqlo U is a collection of Future LifeWear Essentials, designed by Artistic Director Christophe Lemaire and his UNIQLO R&D team in Paris. Together they rediscover everyday clothing through the use of innovative materials and contemporary silhouettes. The collection is carefully designed for every season, with a simplified, modern wardrobe at its core.

The outside of this special material is made of 100% cotton, which provides a smooth and matt feel. The inside is made with the special HEATTECH technology with the characteristic that it absorbs and retains heat to provide continuous heat. Lightweight and comfortable, the new Uniqlo U styles offer flattering silhouettes in an understated color palette. The collection is designed based on the idea that it can be worn under a (sports) jacket or as an elegant T-shirt on its own. The new HEATTECH shirts will be available from today in all UNIQLO stores in the Netherlands and via

HEATTECH was launched by UNIQLO in 2003 from the LifeWear philosophy to make the wearer's life as comfortable as possible. As an alternative to thick, heavy winter clothing, UNIQLO developed a completely new technique together with Toray and its leading fabric technologies. The collaboration resulted in an innovative, thin material that generates and retains heat and can be offered for an accessible price. HEATTECH has been evolving for 17 years and is currently available in three different grades to suit different conditions and situations that have changed winter fashion worldwide.
