How to Choose a Winter Beanie
A good beanie should be warm, comfortable all day and stay put. Look at material, lining and fit.
- Material. Acrylic knits are cheap, colorfast and easy to wash. Wool and merino are warmer for their weight and handle damp better.
- Lining. Fleece or satin linings add warmth and stop itchy knits from bothering your forehead. Satin linings are gentler on curly and textured hair.
- Fit. Cuffed beanies give a double layer over the ears. Slouchy styles look relaxed but are less windproof.
- Thickness. Thin, fitted beanies go under helmets and hoods; chunky cable knits are for town and cold commutes.
Staying Warm in Extreme Cold
In serious cold, exposed skin on the cheeks, nose and ears is the first to suffer. The CDC lists covering the face and ears as one of the basic steps for preventing frostbite, and a balaclava does that in one piece.
- Layer it. Pair a thin balaclava with a beanie or helmet rather than one very thick piece. Layers trap more air and are easier to adjust.
- Manage moisture. Breath freezes in fabric. A mesh breathing panel or a balaclava you can pull down for a minute keeps the mouth area from icing over.
- Bring a spare. On multi-hour days, a dry spare balaclava in your pocket is worth more than a heavier one.
- Know the warning signs. Numbness, pale or waxy skin and shivering that will not stop are signs to get inside and warm up.

Beanie Styles Explained
- Watch cap: a fitted rib knit with a fold-up cuff. Classic, durable and easy to adjust.
- Skull cap: thin and close-fitting, ideal under helmets and hoods.
- Cuffed beanie: the cuff gives a double layer over your ears.
- Slouchy beanie: extra length at the back for a relaxed look; less windproof.
- Chunky cable knit: thick and cozy for town and travel; too bulky for helmets.
- Pom beanie: playful and warm, but the pom does not fit under hoods.
Beanie or Balaclava?
A beanie covers your head and ears; a balaclava also covers your face and neck. For commutes, walks and casual winter days a beanie is plenty. For skiing, snowmobiling, motorcycle riding and windy, sub-zero days, a balaclava (or a beanie plus neck gaiter) protects the skin a beanie leaves exposed. See our guide to the best balaclava for winter.
Caring for Your Beanie
Hand wash wool and fleece-lined beanies in cool water and dry them flat so they keep their shape. Acrylic watch caps can usually go in a cool machine wash. Avoid high dryer heat, which shrinks wool and can melt or pill acrylic.
Choosing a Beanie for Hiking and Camping
On the trail you warm up fast on climbs and cool down quickly at breaks and summits. In camp, you sit still while temperatures drop after sunset. Different beanies suit each moment.
- Hiking: thin merino or light wool blends breathe and stay warm when sweaty. A skull cap fits under a hood.
- Camp: thicker fleece-lined or earflap beanies keep you warm while sitting and can double as a sleeping hat.
- Packability: a light beanie weighs only a couple of ounces and is worth carrying even in summer at altitude.
- Wind and wet: a windproof liner or a hood over a beanie makes a big difference on exposed ridges.
A warm hat is part of the extra clothing in the Ten Essentials, so keep one in your pack year-round in the mountains.

Frequently Asked Questions
What is the best beanie material?
Wool and merino are warmest for their weight; acrylic is cheap and easy to wash. Fleece or satin linings add comfort and warmth.
How should a beanie fit?
It should cover the tops of your ears and stay put without leaving a red line on your forehead.
How often should I wash a beanie?
Wash it every few weeks of regular wear, or more often if you sweat in it. Use cool water, skip fabric softener and air dry.
Is wool or acrylic better for a winter beanie?
Wool, especially merino, is warmer for its weight and stays warm when damp. Acrylic is cheaper, durable and easy to wash.
Should a beanie cover your ears?
Yes. Ears lose heat quickly and are prone to frostbite, so choose a beanie deep enough to cover them or fold the cuff down.
Final Verdict
For cold weather, the ACUSHLA Waterproof Windproof Beanie blocks wind best, and the Smartwool merino beanie is the warmest natural option.
