Got this for a week snorkeling trip in Greece. Great, high quality set – mask offers great view through the tempered glass and is comfortable and snorkel does a great job of keeping the water out and is easy to clear if some does get in. The silicon on the mask is soft and comfortable but it is susceptible to leaking if you've got stubble (like all masks). If you're a bloke and yours start seeping water in, make sure you have a shave!

Decent mask. Alls I read about this mask is "it leaked". If your mask leaks its the wrong size, nothing to do with the mask. Your imstructor should of drummed this into your head. Or if you like snorkeling you would known a mask fits certain faces not all. Masks come in all shapes and sizes so to leave a bad review is not really fair in my opinion. The mask fits me Ok, good quality mask. Masks fog up even the most expensive ones fog up if you breathe out of your nose in them. Another point you should of learned don't breathe out of your nose in a mask the hot air out of your nose will obviously fog the lens. Only downfall about this is I would of liked a box to put the mask in to keep it from being scratched or broken instead of a cressi snorkel bag.

The mask is very good… Best l have had yet. Still fogs up a little, but they all do when it's 38 c outside and the water is colder.
Comfortable mask that fit my face very well, excellent visibility.
The snorkel tube is a little stiff and pulls your teeth so you end up with an aching jaw if you are in a long time, but I imagine it will soften up over time. That said it is easy to clear and barley let's any water in when submerging.
You would need to try it out on your own face but for me it is brilliant and would cost a hell of a lot more to get a better one and even then, unless you scuba a lot, you might not see a difference.

Brilliant snorkel and mask. Use it while snorkelling in the Maldives

I don't care if you're the god of diving masks. If you make them so that the user then needs to pray to heavens that their methods will solve the fogging up then you are not good.
I used every method I found online minus the burning. Why? Oh because the manufacturer doesn't even say if the mask is glass or not. I can assume, but I won't. If I burn it then it's my fault if it breaks.
I bought your Cressi anti-fog spray as well. Not helped one bit.
So here I am in Mauritius with 3 masks from cressi that all fog up. I'm angry. The snorkel that comes with this mask slowly leaks, which is easy to clear if you exhale rapidly to push the water out, but you have to do it OFTEN. Maybe 20-30 seconds. That is unacceptable.
The good thing is that the mask is comfortable to wear.
I got to say – the extra vision needs getting used to. You can think there's something coming your way in your peripheral vision only to realise the extra angles this glass picks up just showed you your own hands holding a GoPro. It's interesting, but needs getting used to.
You can expect an experienced diver to know what to do with your masks. Sadly, you provide ZEROOOOO instructions in the manual attached with this mask. You don't even say a single thing about preparing it. Not one note about "use toothpaste" or whatever. NADA. So you rely on your customers to go on Google and try various stuff. Buy different toothpaste, sprays, etc. not that you care, right?
My 20 yeard old mask that I bought as a kid only needs spit and it never was prepped or washed with toothpaste.
So how is it that in modern times a famous diving gear manufacturer can't make a mask that isn't fogging up?

Having used cheap rubbish before you can really tell the difference going to a better brand. I used this snoring in Barbabdos and it brought me hours of joy. Do a bit of research on how to stop it fogging up though, that’s a skill and not something unique to this mask. The snorkel itself works a charm and prevents and water from entering your mouth, and the mask itself doesn’t leak at all if you get the fit right. Totally worth splashing out the extra cash for a snorkel and mask!

Recently arrived back from holiday and found this mask and snorkel really good . Nice clear vision and excellent fit . One thing you need to be aware of is that if you look straight ahead the valve in the top of the snorkel closes to prevent water ingress when you may not have expected it to . I think this is also because the snorkel is curved backwards following the shape of your head. But overall i think it is worth paying that bit more for the quality.

Great no problems
