Me encanta

Me encanta, tamaño ideal para proteger la cara, cuello y escote. Se puede plegar para llevarlo en tu bolso o mochila. Perfecto para esos días de playa y piscina en verano. Mi piel sensible y con alergia al sol agradece una protección así.

Buenas dias señora,

Saber que su piel sensible y con alergia al sol agradece este nivel de protección es lo más importante para nosotros. Le agradecemos de corazón su confianza y el haber compartido su experiencia.

Well made and beautifull

I love the hat! It’s beautifull, well made and comfy.
I’m considering buying some uv clothes but they are really expensive. However, the quality of the hat makes it more likely I’ll buy a dress or shirt too.
When I made a mistake in my order they were really helpful in sorting it out for me. I recommend this store to everyone!
