Product Customer Reviews

The glasses are advertised to be water repellent but the water droplets don't flow on the glass. On top of that, fog appears on the inner side of the glass because the glasses are too close to the face and the wide temples and frame don't let the air circulate. I have tried them in central California and south California. Last, the glass is orange so it changes the perception of the water. The only good thing is the strap, it holds well. I will probably return them.
If you have a big head, you will either not be able to put these on or you will hurt your face every time you do :-( That's what happens to me and my head is shaven clean so it's not hair in the way! They're otherwise good glasses (5 stars if the strap was long enough)
Got these quickly to replace a lost pair for holiday and if anything found these to be better fitting,protection from water spray and not so dark as the last expensive other brand.. The fit is excellent as the plastic slider at the back keeps the glasses tight to the face making you feel confident they don't come off when you plough head first into the sea. Great all round protection for a price that's hard to beat.. Definitely recommend.
Brýle díky šňůrce neztratíte, kryjí do Re zrak před slunečním zářením.
verwende dieses Brille zum wakeboard und bin sehr zufrieden mit dem Produkt. Kann es jeden der eine Wassersportart macht nur wärmstens empfehlen.
Zuerst dachte ich, die hätten mir eine Kinderbrille geschickt. Kopfband passt selbst in der äußersten Position nicht.
So stelle ich mir eine Brille mit den angegebenen Produktmerkmalen vor.
Sehr praktisch bei kitesurfing!
Perfekte Passform. Leicht einhändig zu verstellen. TS
Al no tener material que amortigüe el roce, llega a doler al tenerlas puestas. En una hora me dolían las orejas. deberían de ponerle material que alivie el roce.
estas gafas tienen un campo de visión muy bueno y muy buena protección solar.
Tengo córnea gutata, necesito la maxima protección solar y de momento está ha sido mi mejor opción. Puedo ir a la playa sin que sufran mis ojos y si se las lleva una ola.. te compras otras !!
Gafas muy bien diseñadas para Kite. La protección 4 hace que no veas demasiado bien si no es un día demasiado luminoso, por lo que no es como si uso para días nublados. No se empañan y el ajuste con la correa es perfecto y fácil de usar con una sola mano mientras estas navegando.
Tras un dia de prueva, puedo decir que me han convencido. Paran bien el viento y las salpicaduras de agua, se mantiene una visión correcta a pesar de las caidas al agua. La protección solar es muy buena, son cristales muy oscuros y polarizados, puedes mirar relajadamente el aguua y el cielo sin forzar los ojos. La sujeción es muy firme, la cinta de detras no es flexible, lo que hace que una vez ajustada las gafas no se pueden salir de su posición en la cabeza. El ajuste de la cinta trasera se puede hacer con simple gesto con una sola mano y mientras las llevas puestas. En general, lo encuentro un producto muy bien pensado y perfecto para practicar Kitesurf.
Je suis très content de ces lunettes, qui couvrent très bien le champ de vision dont la réverbération, et qui sont confortablement installées sous le casque. Malheureusement, lors de ma deuxième sortie avec, un verre s'est détaché et est tombé dans l'eau à la suite d'une chute (un soleil lors d'un waterstart). Je n'ai pas eu l'impression que la chute soit excessivement violente, je n'ai eu aucune douleur ni étourdissement, et la monture ne montre aucune fissure. Dommage, surtout que les produits de kite sont "hivernés" là où je suis donc pas possible de réparer ou changer rapidement...
