The GAS-320 vest and hoodie set features a three-piece design: a padded vest, a hooded sweatshirt, and sweatpants. The overall style leans towards the currently popular sporty-casual and street-style preppy look in the children’s clothing market. This design not only creates a visually layered look but also ensures warmth, freedom of movement, and seasonal adaptability, making it ideal for autumn, winter, and early spring sales.
The vest uses horizontal quilting, providing ample padding without being bulky. Contrasting lettering on the chest and pockets enhances its recognizability. The inner hooded sweatshirt is made of soft fabric, with prints on the sleeves and hoodie echoing the vest’s details, maintaining a unified style. The bottoms are elastic-waisted sweatpants with side color blocking, continuing the overall color scheme. They are comfortable to wear and suitable for everyday wear, outings, and school settings.

• Logo Customization: We support various techniques including embroidery, screen printing, heat transfer, and patches. Choose between subtle or highly recognizable logos based on your brand positioning, suitable for the chest, vest side pockets, cuffs, or trousers.
• Pattern and Print Design: Clients can provide existing design files, or we can assist in simplifying or redesigning them to better suit children’s clothing sizing and mass production processes, avoiding distortion issues in later mass production.
• Color and Fabric Matching: Colors can be matched according to Pantone or physical color charts, supporting the development of multi-color combinations. For fabrics, we can select different weights and feel options based on the target market, striking a balance between cost, comfort, and durability.
