Why Go for Wool?

A lot of winter hats and beanies are knit with acrylic yarn, which is a synthetic material. As we discussed with sweaters and scarves, these synthetic materials are not great for human health or the environment in the long run. They’re petroleum-based materials that can contain chemicals that are potentially toxic to human and environmental health.

That’s why many people are opting for natural materials instead, whenever they can. Wool is an incredibly warm and durable material that’s also non-toxic and biodegradable at the end of its life (as long as it’s not treated with toxic dyes or finishes.) Plus, when done responsibly, wool does not require that any harm comes to the animals from which it’s sourced either.

Look for brands using Climate Beneficial Wool, which has been verified as regenerative by Fibershed, and Responsible Wool Standard (RWS) wool, which ensures a “standard that addresses the welfare of sheep and the land they graze on.”

Types of Wool

Different types of wool have varying pros and cons. Merino wool, which comes from a specific kind of sheep, is softer and lighter weight than most other types of sheep’s wool.

Cashmere comes from the undercoat of a certain kind of goat that lives in the Himalayas. It’s softer, finer, and more luxurious compared to most other types of wool, but also tends to be more expensive and less durable.

Alpaca wool is the best of both worlds: it’s soft and lightweight, but also very durable and temperature-regulating. It’s also relatively rare, so it can be more expensive.

Yak wool has a lot of the same benefits as alpaca, but at a more affordable price point.

Lastly, recycled wool of various types is a great option because it keeps materials out of landfills and reduces the amount of virgin material needed to be sourced from animals.

Other Materials for Winter Hats & Beanies

If you don’t like wool or try to stay away from animal-derived products completely, some of the brands below also use natural and eco-friendly materials like organic cotton. Although it’s not quite as warm or durable, organic cotton is a great non-toxic and vegan alternative to wool hats.
