What kind of fabric is the 'fleeceback jersey' mentioned in the sweatshirt description?
This question seeks to understand how the lining texture and warmth differ from standard sweatshirts after seeing an unfamiliar fabric name in the material guide for the HALF DOME HOODED SWEATSHIRT.
It refers to a fabric knitted smoothly on the outside, while the inner side touching the skin is brushed to create a soft fleece nap.
When you put on a sweatshirt, the inner side is what touches you first. The FLEECEBACK jersey mentioned in the description refers to the way the back of the fabric is processed. Jersey refers to a knitted structure looped with yarn that offers excellent stretch, and fleeceback means a method where the fibers on the reverse side are brushed out like combing to raise a soft fleece. Air is trapped between the raised fleece layers, keeping body heat warmer than a typical single-layer knit.
GRAMICCI's HALF DOME HOODED SWEATSHIRT is crafted from this fleeceback jersey fabric[1]. It is thick. While the outer surface has an even and smooth knit grain, the inner side touching the body is brushed like down, offering a cozy touch. The material blends 87% cotton with 13% polyester[2]. Based on the general softness and sweat absorbency of cotton, blending polyester reduces shape distortion after washing and supports the inner fleece so it does not easily get crushed.
hmmm, it is a structure neatly filled on the inside so that you can wear it reliably like a light outer layer even in chilly weather, while maintaining a neat appearance on the outside.

The specific thickness of the fabric or weight per unit area has not yet been confirmed in official materials.
