Frozen dome? Try one of these.

Icebreaker Chase Beanie ($25)
Don’t let falling temperatures keep you from getting your sweat on. Thin merino wool, like the kind used in Icebreaker’s Chase beanie, is ideal for arduous winter activities, wicking moisture to help you stay dry and warm. Bonus: it doesn’t trap stink.

Carhartt Ear-Flap Cap ($25)
This hat is for people who live life headfirst. Whether you need to check under the hood when the wind’s blowing hard or schlep to the subway in a blizzard, the insulated polyester flaps shield your ears from the worst of winter’s chill and fold up and out of the way when you don’t need them.

Toad&Co Flurrie Beanie ($39)
The Flurrie is made from a well-spun blend of plush lambswool and sturdy nylon for added durability, with an inner microfleece headband for comfy softness. The contrasting shade on the flipped edge will kick your style points up a notch.

Skida Alpine Hat ($36)
Stand out from the crowd. Skida’s Alpine hat (women’s pictured) comes in more than 20 patterns. The poly-blend outer and fleece liner are perfect for winter runs and maintain a low enough profile for optimal layering and heat retention.

Stormy Kromer Button Up Cap ($45)
The Button Up sits squarely at the crossroads of function and fashion. The pull-down earflaps keep your head and ears toasty when the weather turns sour, while the simple side button adds a touch of urban chic to that timeless Stormy design.

Turtle Fur Slater Ragg Knit Beanie ($30)
Don’t be fooled by the ribbed exterior. The fatal flaw of the wool beanie—the fabric’s itch-inducing texture—is rectified by the Slater Ragg’s microfleece liner. Plus, that ribbing lends the hat a classic look and an accommodating bit of stretch.
