The warmth of the Aurora beanie is provided by mohair and merino wool. In addition, the beanie contains polyamide, which improves durability and speeds up drying. The knit style offers a bit of an enhancement to insulation, and the folded sides give your forehead and ears extra warmth. The Aurora is a good choice even for harsher freezing conditions, as well as for use where you remain stationary for long periods and the body does not generate much heat. - 50% mohair, 32% polyamide, 18% extra-fine merino wool - Metal logo - Machine washable at 30 °C on a gentle cycle; do not use bleach or fabric softener; dry flat at room temperature This product is, quite naturally, a mulesing-free product.
