The product is made of new Smith velvet knitted fabric, which has stronger warmth retention than ordinary sweatshirts, is not easy to pill and fuzz, has a drapey feel when worn, and has a soft and delicate feel. The whole garment is in the shape of a loose cardigan, with slightly dropped shoulders to fit the Asian body shape. Most of the tailoring uses traditional flat seam technology, with smooth stitching. The fabric is connected by double-needle lathes to achieve the effect of good resilience and resistance to deformation. A multi-color display with multiple choices and low saturation, satisfying cleanfit enthusiasts and daily commuters with multiple choices.
