The basic rule is to achieve a balance between warmth, durability, and easy care. You’ll find options made from acrylic and wool blends, sometimes with polyamide and other materials like cotton or polyester. For example, some pullovers use a mix of acrylic and polyamide with sheep wool, while others use a polyester-acrylic-wool-elastane blend for extra flexibility and warmth. This variety lets you choose the right weight, high durability, and everyday wear comfort. Make sure you know the available sizes—some styles come in size ranges like S to XXXXL, while others offer one-size options. Also ensure the colors suit your everyday wardrobe.
