Should I wear a hat while jogging to keep warm in winter?

When jogging in cool conditions, a hat can do more than just keep you warm. Here are the most important benefits and tips at a glance:

Benefits of a hat when jogging

Thermal protection & temperature regulation
The head and ears are particularly sensitive to cold. A breathable hat keeps you warm without overheating.
Moisture management
Sweat is absorbed better and does not run into the face or onto the glasses.
UV & weather protection
Lightweight hats with UV protection protect against the sun. Thick hats offer additional rain protection in drizzle or snow.
Focus & Comfort
Without cold or wind in your head, your concentration on the run remains optimal.
Light compression
Unconsciously, a tight-fitting hat helps to stabilize the head and neck muscles.

Note the material:
Merino wool keeps you warm and wicks moisture—ideal for temperatures below 10°C. Synthetics are excellent for milder conditions or indoor runs.
Fit matters:
Too loose and you lose warmth; too tight and you're uncomfortable. Try to find a good fit and stay flexible with a washable elastic waistband.
Seasonal adjustment:
In winter, thick lining plus fleece are better, in spring, thin and breathable – this way you can cope with any weather condition.

“At what temperature should I wear a hat?”
From about 10 °C: thin headcap, from 5 °C a wind-stop hat, from 0 °C or in strong winds: thick winter beanie.
“Which is better: wool or synthetic?”
Wool keeps you warm even when wet; synthetics dry faster. Merino wool is highly recommended for longer runs.
“How do I care for running hats?”
Hand wash or delicate wash at 30°C. Remove pilling by hand; do not tumble dry.
