Common materials include fleece and polyester, cotton or cotton/poly blends, acrylic knit, high‑pile fleece, and thermal fabrics with poly‑spandex blends (for example, 90% polyester/10% spandex in some thermal shirts).
Most items list machine wash and tumble dry; a few knit pieces recommend line drying or laying flat to dry.
Features that add warmth include plush or high‑pile fleece linings, double‑sided or ultra‑thick fleece construction, oversized hoods, large pockets, and fleece‑lined thermal layers.
Some items use breathable fleece that insulates without causing overheating, while others use double‑sided or high‑density fleece for extra warmth. Thermal pieces often combine a fleece lining with moisture‑wicking fibers to keep wearers warm and dry.
Sizing is mainly listed as Kids or Girls. Several items show specific ranges such as 3T–12, 3–12 years, 4–12 years, and one 'one‑size' listing noted as suitable for kids about 6–14 years—the exact labels vary by item.
