This three-piece set, consisting of a vest, hoodie, and casual sweatpants, is a highly practical sweatshirt set solution launched by Heyisenlin for the children’s and youth markets. The overall design revolves around the core concept of “layered dressing,” combining a thick vest with a sweatshirt and sweatpants to meet the needs of various scenarios in autumn, winter, and early spring. It provides warmth without being bulky, making it popular with wholesalers, brand clients, and cross-border e-commerce buyers.
Aesthetically, the set features a 3D quilted vest paired with a hoodie, and jogger pants, creating a casual, sporty, and everyday school look. The vest incorporates practical pockets, enhancing both visual appeal and functionality. The sweatshirt and pants maintain a harmonious proportion, resulting in a cohesive look, making it ideal for sale as a set or as a key brand item.
In terms of fabric selection, this vest and sweatshirt set adheres to the principles of “durability, ease of care, and suitability for mass production.”
The vest typically uses high-density polyester fabric with a stable filling structure, ensuring warmth while controlling overall weight for easy movement during children’s daily activities. The sweatshirt and sweatpants are primarily made of soft knit fabric, balancing skin-friendliness and washability, suitable for frequent wear and repeated washing.
In terms of craftsmanship, the vest uses a regular quilting process, which helps to fix the filling layer and prevent shifting after washing. The hood, cuffs, and hem of the sweatshirt have undergone repeated pattern making and testing to ensure comfort and resistance to deformation. The sweatshirt uses an elastic waistband combined with a drawstring design to fit different body types and reduce sizing complaints. These details are the result of Heyisenlin’s continuous optimization and refinement based on years of actual order experience.

As a Chinese hoodie manufacturer specializing in customized hoodie sets, Heyisenlin offers mature and flexible OEM and ODM customization services, helping clients upgrade from “generic” to “brand-specific” designs.
For logo customization, we support various common techniques such as embroidery, screen printing, and heat transfer, allowing clients to choose more washable or decorative options based on their brand positioning.
For pattern customization, whether it’s simple lettering, sporty elements, or brand IP visuals, we can create samples and mass-produce based on the design drafts.
For color customization, the entire garment (vest, hoodie, pants) can be designed with either a unified or contrasting color scheme to meet the color preferences of different markets.
At the design customization level, clients can not only adjust fabric and pattern details but also further develop designs such as pocket structure, zipper style, and hood shape, truly creating differentiation.
For clients who wish to enter the market quickly, we can also make minor modifications to existing mature patterns, significantly shortening the development cycle and reducing initial investment risks.
