A pretty decent mask.
So far it is the best I have. Comparing to my other masks, I will mention the Aqualung Sphera that I love but it held only 2 years before started leaking at higher depth, and Mares x-force that is very good in many terms but not that low volume, the XDream is probably the best one I owned so far. I like the nice grip for the fingers to squeeze up the nose, a very low volume design and ease of shuttling air into the eye area (it always reaches the mask and isn't pushed outside no matter how I wear the mask - very good feature), pretty decent sealing (to be objective not the best though), I would say a good observation angle and low distortion of the lenses in my experience, comfortable design, and good adjustable band that does the job just fine. On the downside, I have some kind of rubber odor, I don't like it, it is not that strong, but after three days of diving it is still present, and in my experience the lenses begin catching fog a bit too quick comparing to the other freedive dedicated masks I own.
