Compare the weight of the Summer Yarn vs Winter Yarn when selecting your beanie for today:
Winter Yarn is usually made of 100% Acrylic. It is similar to wool in that it holds in heat, but without the itchy/scratchy feeling. The material is super soft, non allergenic, and provides a hefty body for the slouchy styles.
Lightweight Summer Yarn is usually made of 100% Cotton. The cotton breathes very well and does not retain heat. Summer cotton styles weigh about a quarter of the weight of the winter styles and offer a little more drape in the body of the slouchy-style beanies.
