Bloc Chameleon X400 Shiny Black S11 Cat 3. Smoke Lens

A good product, delivered on time.

These are great glasses for the glacier - the foam gasket is held tight with a magnet on the rim and faux-leather bits on the side. It works quite well and is slightly vented to avoid misting. I think the gasket fit could have been a bit better around my face, but maybe that is just the shape of my bonce! The hooked arms keep them locked onto your face too.The great thing is you can take off the gasket and replace the hooked arms with the straight ones and you have a perfectly normal looking pair of glasses for town!

Great quality product at a great price, don't go for the even cheaper glasses if going mountaineering...

Very dark

They broke in less than 1 week

These are nice glasses, but they are Category 4, not Cat. 3 as advertised (Bloc don't make them in Cat. 3). They come with in a soft material Bloc bag, the inside of which can be used to clean the glasses. They also come with two set of arms that are interchangeable. One pair is malleable and can be bent around your ears to hold the glasses tightly to your face.

My husband loves them for skiing
