Not water repellent

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.

Strap is too short!

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)

Great protection from sun and water spray

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.

Sportliche Brille mit zu kurzem Kopfband

Sieht gut aus und sitzt. Bei einem Kopfumfang von 60 cm passt das Band nur knapp, wenn es auf volle Länge gestellt wird.

Kopfband extrem klein / eng

Zuerst dachte ich, die hätten mir eine Kinderbrille geschickt. Kopfband passt selbst in der äußersten Position nicht.

Rundum gut und angenehm zu tragen

So stelle ich mir eine Brille mit den angegebenen Produktmerkmalen vor.

Sehr praktisch

Sehr praktisch bei kitesurfing!

Top Kitebrille

Perfekte Passform. Leicht einhändig zu verstellen. TS


Si buscas una gafa OSCURA, con alta protección y cómoda, esta es la mejor que conozco. La utilizo para trabajar en el mar, y es muy recomendable.

Muy buena proteccion

Las compré para kitesurf y paddle surf y cumplen más que de sobra con su función. Muy cómodas, tapan por completo al pegarse a la cara e ideal la cinta de sujeción. No se afloja.
