Estupenda calidad,
Bonito y buena calidad
Muy bonito, buen precio, la tela se mancha y cuesta quitar manchas
El producto es estupendo, tiene un uso magnifico y su secado fácil y que el sol y cloros de oiscinas no lo transforman, son sus mejores cualidades.
No se llena aire. Muy comodo. No se empapa de agua.
Cómodo y ajustable
Es in bañador que regalé, queda muy bien puesto y tiene una combinación de colores muy original y bonita, sin ser cantona
Se seca muy rapido
Es un bañador muy cómodo el único defecto que le veo es que cómo lleva el velcro a veces me molesta. Por mi sería el bañador perfecto con goma sin velcro ni cordones.
a mi hijo le gusta mucho, seguramente se lo comprara en otro color
Cómodo para el baño y para estar con él puesto, seca rápido
Muy buen bañador en calidad y precio, muy práctico y cómodo
tres bien et pas cher

Product name
Why Guethary? All swim trunks n the Tribord range are proudly named after beaches in Basque Country. Guethary trunks pay homage to 1970s trunks, as much by their colors as by their shape (short with a flat waistband). Just like this beautiful village overlooking the Atlantic, they are designed for surfing enthusiasts! Tribord brand products are devised, designed, and developed at the company’s headquarters, located by the Atlantic Ocean, in Basque Country, in the town of Hendaye.
