The North Face Beanies

When it comes to keeping warm, natural fabrics are your best bet. Wool is the warmest option. But if it feels itchy, go for merino wool – it's softer. A merino wool beanie is perfect for outdoor activities, it keeps you warm in the cold and cool in the heat. Plus, it wicks away moisture so you don't get wet.

Synthetic fabrics like acrylic and polyamide won't keep you as warm, but they offer protection from the wind or bad hair days. They can also make your hair static.

For outdoor activities like running, hiking or gym sessions, a breathable beanie is essential to avoid unpleasant odors. Look for thin and lightweight beanies so it can protect you against wind while being comfortable to wear. And you should easily store it in your backpack or pocket when not in use.
