Features and Construction

This jumper features several distinctive design elements that contribute to its casual appeal and practical wearability. The combination of rainbow stripes and hollow knit texture creates visual interest without adding excessive weight or bulk.
Material and Build
Constructed primarily from polyester fibres, this jumper utilises hollow knit techniques to create texture while maintaining lightweight properties. The medium thickness fabric provides sufficient coverage for cooler weather while remaining breathable enough for transitional seasons. This construction approach allows the colourful striped pattern to stand out with dimensional interest while ensuring the garment retains its shape through regular wear and washing according to standard polyester care guidelines.
Size and Practical Fit
The free size design with loose fit accommodates various body types without requiring specific measurements. Batwing sleeves contribute to the relaxed silhouette by providing extra room through the arm area, creating a contemporary look that contrasts with traditional fitted sleeves. This sizing approach makes the jumper accessible to different wearers while maintaining the casual aesthetic central to its Japanese and Korean style influences. The round neck completes the classic pullover design, ensuring easy pairing with various tops and accessories.
