Characteristics of the sandwich hyaluronic acid thermal clothing.

 "Sandwich" structure
Meaning: Refers to the woven structure of the fabric, which is divided into three layers like a sandwich.

Typical structure:
Outer layer: It typically employs fine, wear-resistant, and anti-pilling fibers (such as polyester and nylon) to serve protective and aesthetic purposes.
Intermediate layer: The core thermal layer, typically made of breathable thermal materials such as fleece, wool, acrylic, and unique thermal fusion fleece. This layer can trap a large amount of still air, effectively retaining body heat and achieving lightweight warmth.
Inner layer: skin-friendly layer, usually specially treated.
Features: stable structure, good warmth retention, breathable and moisture-wicking, and resistant to deformation.
