Texas summer! We need to protect ourselves from all those harmful UVs and these whimsical reversible hats would do the job.
Back home in Malaysia, where it is hot all the time, we do not wear hats, instead we carry an umbrella. Over here in the States, no one carries an umbrella unless it is raining, even then... it's much to be desired. Talk about culture differences. Both ways are to protect oneself from the scorching sun, yet we have different ways of doing it. How strange?
Perhaps hats are more of a fashionable accessory while an umbrella is cumbersome? Or perhaps you can match a hat to your outfit while an umbrella, well.. not easy. Think about it.
