Many women's stocking caps are made from acrylic (either 100% acrylic or acrylic blends). Other listings use polyester or polyester linings. Some examples of blended mixes shown in product details include 70% acrylic/30% polyester and 95% acrylic/1% polyester.
Many caps include a soft inner lining such as fleece or polyester. Several use double-layer construction or a smooth interior lining to add extra warmth and comfort.
Care varies by style: many list hand wash and lay flat to dry; some note machine wash and tumble dry; and certain graphic or printed caps advise spot cleaning or line drying.
Most are pull-on, stretchable beanies offered as one-size/adult general sizing or designed with a stretch-fit. Some product listings also specify stretch ranges for head circumference.
You’ll find cuffed beanies with folded brims, relaxed slouchy beanies, and low-profile skull-cap or cuffed knit styles. Most use pull-on construction with a stretch knit.
Crown heights vary across styles; the available details show values ranging from about 1.5 inches up to 8.7 inches.
Listings use a few fabric-weight labels: some specify lightweight, others midweight, and several describe the construction as suitable for year-round wear.
