I spent 6 weeks testing 7 different brands of cute winter beanies for teenage girls. It is hard to find hats that are both stylish and warm enough for freezing weather. Teenagers need protection without looking bulky. Our testing showed that function often beats simple style when the temperature drops.

We compared the winning 3-in-1 model against a popular high-end pom-pom hat (Brand A) and a budget fleece option (Brand B). The results show a clear difference in protection versus price.
