跟ZARA、H&M等以“快”和“量”为主，质量次之的同类品牌相比，优衣库选择的几乎都是业界前列的产品生产和供应链体系，通过减少设计和少用繁杂面料来降低成本，整体出品质量较高，稳定性强。
 
In the leggings market, Uniqlo's Heattech series has been a great deal since its launch, and the annual change of seasons will bring steady sales to the brand, but despite the mediocre quality of Heattech tights with the concept of "heat", in addition to high comfort, it is not even comparable to Chinese brands such as Antarctica in terms of warmth and durability.
 
The Heattech series of jumpsuits is also made of cotton and spandex fabrics, which are generally thin, and the official claim has a slight sense of pressure, but in fact, the body cannot be experienced, and there is no shaping effect, and the pilling condition has been more serious, and it is easy to have holes and other damage after long-term wear. Of course, the comfort characteristics of UNIQLO's clothing are not absent in the tights, and the stress-free restraint shows the high comfort of the Heattech series that is easy to put on and take off, and the design of the heel section that is not easy to fall off can also add points to the experience.
 
In addition, the HEATTECH series also has an extra warm very leggings, which are mainly made of viscose, acrylic and polyester fibers, which have a stronger warmth effect than the onesie pantyhose model, and have more elastic strength and higher body tolerance. However, due to the large use of acrylic, it is easy to generate static electricity in autumn and winter, and it is slightly inconvenient to layer hakama.
 
UNIQLO's HEATTECH series is priced at 79 yuan a piece, and there are few discount periods, compared with Japanese pantyhose at the same price, there is still a big gap between the warmth performance and shaping effect of this series, which is suitable for people who pursue comfortable and light tights.
