Across the listings the sweaters use a few different materials: a viscose blend (listed as 49% viscose / 28% polyester / 23% nylon), acrylic, and polyester.
The listings indicate both lightweight and midweight knit fabrics.
Care guidance varies but generally recommends machine washing (one listing specifies “Machine Wash Cold with Like Colors”) and drying by line dry or laying flat to dry. A cropped sweater description also confirms machine washability.
All listings use a crew neckline. Cuff treatments vary and include ribbed cuffs or styles without a defined cuff.
If wrinkles appear from packaging, the descriptions recommend a quick wash or a light ironing to restore a smooth, ready‑to‑wear appearance.
Specific sizes shown in the listings include X‑Small, Small, and X‑Large; at least one description also notes that the sweater is available in multiple other sizes.
