Which winter hat is best? While you only lose 10% of your body heat through your head, you still want to cover up your noggin while temperatures are on the colder side. Even if you think you have all the winter hats you need, you might find something that piques your interest here. The beanie is the most popular type of winter hat, but there are several other styles to add to your winter wardrobe. For a classic that never goes out of style, the Carhartt Knit Cuffed Beanie is the top choice. What to know before you buy a winter hat Styles Here are the most popular styles of winter hats: Beanie: The beanie is a cold-weather staple. Unisex and simple, you can wear it with any casual outfit. It pulls close to your head, making it of the warmest options, especially if you invest in one made of wool or fleece. Bobble beanie: Bobble hats feature a ball of yarn or fur attached to the top, also known as a pom-pom. Some bobble hats feature a tassel. The bobble is decorative, and this casual style is popular with kids and adults alike. Flat caps: The flat cap is an outdoorsy but dressy hat that features a small, stiff bill. It is also called a newsboy or golf cap. It comes in traditional materials, such as wool tweed. Warm baseball hat: If you can’t part with your baseball cap in the winter, consider one made of materials that will trap heat, like tweed, flannel, corduroy or wool. These warmer materials elevate your look while still being sporty. Trapper or aviator hat: Possibly the warmest winter hat available, the trapper or aviator hat features earflaps that secure under your chin with straps. They’re typically lined with fur, sherpa or flannel for extra warmth. The shell can be made from a range of materials such as cotton, polyester, flannel, fur or leather. Material The biggest factor of warmth in a hat is the material used. Cotton is an inexpensive, lightweight and breathable material. However, it’s not insulating enough for freezing weather and doesn’t repel moisture. Acrylic is an affordable alternative to wool and is often used in beanies. The synthetic material is soft and easy to clean, but it’s not as warm as wool. Quilted nylon or polyester are more water-resistant than natural materials and are often used in the shells of winter hats. Wool is a naturally insulating, warm material that also has moisture-wicking and water-repellent properties. It’s not as easy to clean as cotton or acrylic hats. Felt is used in more fashionable styles of winter hats. You’ll typically find it in hats that have brims. Felt is made from pressed fibers, either wool or synthetic. Fur is used in traditional, trapper-style hats or cossack hats, which are all-fur hats without ear flaps. Real fur is warm, but it requires professional cleaning. You can find faux fur alternatives that are easier to clean and less expensive. Fleece is either made from wool or synthetic fibers and features a thick pile that’s soft and stretchy. Fleece is warm, retains body heat and is relatively easy to clean. What to look for in a quality winter hat Lining Lining serves as an extra layer that can provide added insulation to retain body heat. Depending on the material, a lining can also wick sweat away from the body. Plush, cozy lining, such as sherpa, provides extra comfort. Ear flaps Lined ear flaps are a feature found on all aviator and trapper-style hats. They provide warmth and protection from the elements. Most ear flaps flip up and attach to the hat when not in use, or you can fasten them under your chin to keep out the wind. Cuff Beanie-style hats can come with a cuff that folds up for extra warmth around your ears. They can also be uncuffed for a slouchier appearance. Some cuffed beanies are sewn in place and are less versatile. Texture Winter hats vary in texture from smooth felt to chunky knits. Beanies are often ribbed, though you can find cable-knit ones. Tweed and corduroy hats have distinct textures. Fur and faux fur hats are fluffy and soft. How much you can expect to spend on a winter hat Pricing entirely depends on the material, style and brand name. For example, an off-brand beanie will be cheaper than a name-brand fur cap. More affordable winter hats start at $7, but they can cost upwards of $70. Winter hat FAQ What kind of hat will keep me warm throughout in the winter? A.
