Envío en dos días, perfecto. <br /> La funda estupenda (no estaría de más una pequeña cinta o cordino en el agarre de la cremallera). <br /> Material de calidad y bien adaptado a su función. Las primeras pruebas, excelente. <br /> Las patillas y cinta intercambiables son muy útiles cuando pasas de correr a la bicicleta o la montaña. En trail buen ajuste; pasan los kilómetros y no sientes que las llevas. El aplique para graduar bien, lo he puesto progresivo y va estupendo para los cambios cerca-lejos (suelo / fondo, pisada / fondo, GPS o reloj / fondo, presa o reunión / top). Para dar una orientación, poner los cristales graduados progresivos me ha constado 100€ en mi óptica. <br /> Estupendo poder pedir recambios, y que casi todo sea desmontable: gran idea. <br /> Los tornillos del soporte a la nariz un poco endebles. <br /> Creo que debería haber dos tallas para poder escoger la más ajustada a cada cara. Me quedan un poco grandes. <br /> En la publicidad se puede llegar a pensar que vienen con dos cristales intercambiables. Esto debería ser más claro. <br /> Con mascarilla se empañan. <br /> Recomendables.
I am very pleased with my last pair of glasses designed for montain bike OS399
Ottimo prodotto e spedizione rapida... molto comoda anche la fascia elastica.
Really good sunglasses. Love to use them.
